Trigger Pull: The trigger pull on the Stainless Ruger Mark IV Break Barrel .177 Cal Pellet Pistol is not too bad, we feel it is a around 6-7 pounds or so without measuring. In comparison to a real steel 22LR semi auto SAO trigger pistol, the trigger is much heavier but most of these 22LR pistols of this nature have what we would consider to be near perfect triggers. Over time once you get use to the pressure and release point accuracy with this pistol it is for sure possible.

Accuracy: We have tested out the black version of this pistol which will perform exactly the same or should we say is expected to perform the same since they are virtually the exact same Pellet Pistol but in different finishes. In this Field Test Shooting Video we put some lead pellets in the Pellet Pistol to see what the real world velocity is compared to the claimed fps. We also put 7 rounds into a paper target setup 30 feet downrange to find out just how accurate and what kind of grouping we can get from this compact spring piston replica air pistol! For our Chronograph test we placed 5 rounds through our Chrony using 8.18 grain Sig Sauer Match Precision Wadcutter Lead Pellets and was able to average 312 fps so just shy of the claimed 320 fps but there are lighter lead pellets out there and even lighter alloy pellets so higher fps can be achieved with this Air Pistol if you plan on using lighter pellets. For the accuracy portion we ended up placing 7 rounds into a fresh paper target setup 30 feet down range. We were using our standard seated and rested shooting position which does offer a fairly stable shooting platform but not without some degree of human interaction. We were a little bit disappointed in the 2 inch grouping we got, we were expecting closer to a 1 inch group but we would have had to have been on my game and maybe today we were not. Pellet choice can also effect accuracy for sure and so maybe a different pellet would have performed better in this test. Most of the variable was up and down not left to right with only about an inch side to side.
