Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol Chronograph Test

As promised I did a redo of my Original Chronograph Test for my Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol. The first time around I just could not get my Chronograph to read in the poor lighting I had going on that day. I spent a fair bit of time doing some testing with my Chronograph since it is that time of year when the lighting is poor and determined that I need to use the white defusing panels as it seems that my roofline and the low light are playing havoc with the Chronograph readings.

Once I sorted this all out my Chronograph worked perfectly and I was able to get some readings for you with my Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol. As I assumed I did not get much over 350 fps. I also got a lot of variation in the fps, most likely due to the fact that I had to roll down the pellets a bit on the backside in order to feed them in the barrel from front to back, some pellets where tight and some where a bit looser, the looser ones seemed to shoot a bit faster as less of the pressure may have escaped out the back where the primer was situated.


Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol Field Test Shooting Review

It's a bird, it's a plan, no wait... It's a pellet gun, no it's a cap gun, or is it a blank gun or maybe it's a real gun? Well it shoots lead bullets out of the barrel using gun powder so who really know's what we should call it? At least here in Canada you don't need a license to buy or own the Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol so that's a good thing :)

If you have not already watched my Table Top Review for the Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol, make sure to do so to find out a bit more info on it since I don't go over too much in this Field Test Shooting Review.

So on with the Field Test Shooting Review results... Right off the top, I have no Chronograph test result, try as I did I could not get my Chronograph to read the pellet speed in the rather low light situation I had today, even with a bunch of added extra lights :( I would say off hand that it was shooting somewhere in the 350-450 fps range and when I do get a brighter day I will pop outside and shoot a couple rounds off and post the updated info here for you all, so check back in a bit if this interests you.

What I can tell you for sure is how this gun shot in terms of accuracy. I was expecting to spray pellets all over the target because there is no back sight on the Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol, there is just a post sight up front.  I was not even sure if I was going to get all the pellets on the paper. I even setup my target at the 20 foot mark just to be safe and as per usual I was using a semi-rested position by placing a sand bag to rest my hands on and then sitting on my knees in the back, pretty stable all around.

I started off the target test by aiming dead center but quickly found that I was shooting about 6 inches high, so my next 5 shots I aimed 6 inches below the bullseye and low and behold 4 out of 5 of the shots landed within 1.5 inches of each other. So I guess having a rear sight is over rated! If you can figure this gun out, the rifled barrel will direct each pellet straight and true so I think it really comes down to knowing how to line up the front sight with an imaginary rear sight and don't try to shoot really small targets far away. Once you get used to where to point the Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol, you should easily be able to hit a pop can out to 20-30 feet with no problems.

Of course you have to reload this pistol before each shot which consists of cocking the hammer, placing a pellet in the front of the barrel and pushing it to the back with the loading ram rod and then positioning a #11 percussion cap on the primer nipple. Not a rapid fire gun at all but you do appreciate each shot considering the work involved. I also found pre-rolling the back side off my pellets helped to reduce the rear diameter so that the pellets loaded into the barrel much easier. You may have to blow out some residue between each shot which is not something I would recommend with most guns but it's very clear that this pistol is safe since in order to see the barrel obstruction there would be no percussion cap loaded onto the gun.

The Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol is a very unique pellet pistol and actually kind of fun to shoot since it involves a bit of work for each shot and of course some hands on time to figure out exactly how and where to point it to get accurate target results.

Make sure to watch my second Chronograph Test where I was able to get some readings for you!


Pedersoli Derringer Guardian #11 4.5mm .177 Pellet Pistol Table Top Review

Type: Pellet percussion cap parlor pistol.
Manufacturer: Davide Pedersoli.
Model: Derringer Guardian #11.
Materials: Mostly steel.
Weight: .34 pounds (155 grams)
Barrel: 3 1/8 inch steel rifled.
Propulsion: #11 percussion caps.
Action: Single shot, single action only.
Ammunition Type: 4.5mm BB's / .177 Caliber Pellets.
Ammunition Capacity: 1 round.
FPS: Under 500.

Trigger Pull: The trigger pull on the Pedersoli Derringer Guardian #11 is pretty light and short since it is a true single action only pistol, the majority of the pull comes from the pre-cocking of the hammer, there is next to no take-up or creep and I would say around a 2-3 pound trigger pull.

Accuracy: This part of the review is yet to be determined, I don't expect anything special here since there is no rear sight, I am guessing I will need to practice a bit with the Pedersoli Derringer Guardian to figure out how to sight it in using the rear chamber area as a sight bridge. Once I can figure it out I should get decent shot placement since the barrel is rifled. At this point I have no real idea what kind of fps to expect since I have not been able to acquire any #11 percussion caps, but I am guessing it will be just under 500 fps to stay Canada legal as an unregulated or uncontolled firearm. UPDATED FIELD TEST SHOOTING RESULTS HERE.

Build Quality: The build quality in the Pedersoli Derringer Guardian #11 is what you would expect from a true firearm, all the metal parts are actual steel, not zinc like you would find in most airguns. The only exception is the grips which are plastic. The fit and finish is very nice with gun bluing on the steel parts and very good quality control and fit throughout. The only improvement would have been actual wooden grips since the rest of the gun is so well made and finished.

Realism: The Pedersoli Derringer Guardian #11 is a Parlor Pistol designed for "indoor" shooting. (These guns were first developed in 1845 when French inventor, Louis Nicolas Flobert, modified a percussion cap to hold a small lead bullet) So in other words it is a real gun, not so much a replica. The #11 Pedersoli Derringer Guardian version is designed to shoot within our Canada Uncontrolled Firearms limitations so this pellet pistol can be sold within Canada to an adult without the requirement of a PAL Firearms license.

  • Legal in Canada without a PAL Firearms License.
  • Smallest pellet pistol I know of!


  • No rear sight, will take some practice to get used to.
  • Plastic grips.
  • #11 percussion caps are a bit hard to find in stock at times.

When I came across the Pedersoli Derringer Guardian #11 I just had to have one! Heck, it's a pellet gun, and It's kind of a blank gun or cap gun all in one, it's also one of the smallest pellet guns I have ever seen. Like most of the other pellet pistols I own, it does not require a PAL or Firearms license here in Canada and can be shot in a lot more places than a "real gun" or Controlled Firearm can because of the low energy levels it produces and of course lower volume of sound it emits. I suppose it could even be shot indoors if you had the right setup in your house or garage. Definitely one of my most unique pellet pistols I own.
