Trigger Pull: The trigger pull on the Umarex SA10 CO2 Blowback Pellet and BB Pistol is similar to most of the rotary magazine styled pellet pistols. The blowback operation does cock the hammer allowing for a lighter single action styled trigger pull but the trigger pull length is still about the same as shooting in double action. There is less trigger pull weight when the hammer is back shooting in single action but the first part of the trigger pull is necessary in order to rotate the magazine.

Accuracy: As always during our indoor Sea Can Field Test Shooting videos, we first test out the velocity of each gun. Since the Umarex SA10 CO2 Blowback Pellet and BB Pistol can shoot both 4.5mm Steel BB's and .177 caliber pellets we tested both ammo types using our Chrony Chronograph. We fired three shots of each ammo to get an average fps velocity. Interestingly the heavier 6.9 grain lead pellets had the higher average velocity of 376 fps versus 304 fps with 5.1 grain Steel BB's. We have a feeling the lead pellets fit the barrel more snug and did not let any of the CO2 blow by creating more back pressure and a higher velocity. Moving to the accuracy part we were able to get about a 2 inch 8 shot grouping using .177 caliber lead pellets with the Umarex SA10 CO2 Blowback Pellet and BB Pistol. All shots where fairly well centered but we did notice that most shots actually hit all within a very tight 1/2 inch group with 3 shots coming out a bit and extending the grouping more or less vertically. Switching up the ammo to steel BB's and as expected the groupings extended to about 3 inches with one outlier hitting very wide for some reason? Even with the steel BB's shot placement on the target was well centered in general.

Build Quality: The Umarex SA10 CO2 Blowback Pellet and BB Pistol feel great in the hand and has a nice weight and solid feel to it. Like most modern day pistols the Umarex SA10 CO2 Blowback Pellet and BB Pistol has a metal slide and polymer frame, you will also find a lot of internal metal parts along with a full size drop out metal magazine. Fit and finish are also very good.

Realism: The Umarex SA10 CO2 Blowback Pellet and BB Pistol is not a copy or replica of any actual real steel gun in production but to me it most resembles a Sig Sauer, not exactly as the Umarex SA10 CO2 Blowback Pellet and BB Pistol does incorporate its own design and style. You will find a lot of real gun attributes  that make this gun look and feel the deal. Like it's blowback operation, full see drop out metal magazine, wide open recessed barrel and ability to be field stripped.

Pros:

• Great weight and feel to it, build quality seems good.
• Accessory rail for adding a laser or tactical light.
• Unique full size drop out metal magazine that holds extra rotary magazines on it for quick reloading.
• Have the option of shooting Steel BB’s or pellets.
• Has a rifled barrel.
• Gold barrel looks good.
• Barrel tip is removable allowing for possible mock suppressor or silencer.
• Slide catch is actually a safety making it nice and discreet.
• Can easily field strip the gun.
• Warning instruction are not overpowering.

Cons:

• No white or yellow dot sight on the front and they are non-adjustable.
• Trigger safety is just for show.
• Not really a replica but a great looking gun none the less.

Comments: We have been waiting a while to get our hands on the Umarex SA10 CO2 Blowback Pellet and BB Pistol and now that we have it for review We can say it seems to be a really well put together CO2 Blowback Airgun. Of course we still need to get some shooting in with it till we make our final decision but so far we were liking what we are seeing. Generally prefer actual Replica Airguns but the Umarex SA10 CO2 Blowback Pellet and BB Pistol does have a really nice look and feel to it, we don't even mind the Gold barrel and we are usually not a big Gold Gun fan. The unique magazine design with its snap in rotary Pellet and BB magazines should come in handy when it coms time for testing and the ability to shoot either Pellets or BB's does give the shooter more options.
