Solid Contender, Interesting Innovations, Close But Not Perfect.

Picked this up as my first Sig Air pistol, my only previous experience with Sig being the MCX Gen 2, so I will be making a few cross-brand comparisons to the other Air Pistols I own. First Impression: Right off the bat, I have to highlight belt fed magazine and trigger pull had a surprisingly good feel compared to my other belt fed pistol. I've always preferred drop-free magazines with the C02 built in for closer realism than the stick magazine + CO2 in grip you find on some, and the way they managed to combine a belt fed stick into the magazine is pretty genius. It is incredibly painless to reload with a simple push button to release the pellet stick-belt and flipping up the back on that giving you access to half the capacity instead of the tedious one by one like other belt fed models. Economy: CO2 is always gonna get spent quicker with GBB, I put through 3x 20 round magazines on my first 12g C02, unfortunately do not have a chronograph set up to document the pressure drop off, but maybe could have pushed a 4th. Build: The field stripping is a nice feature but now we get towards a couple of the things stopping this from being next level, I wish it had a working slide catch, that would have been a nice touch despite not being essential for operation. And perhaps a little more glaring is the glossy polymer frame does look and feel a bit toward the toy aisle end of plastics than others. The texture could prolly use just a touch of sanding with a high grit and it would feel a little better on the skin, I feel this may be a result of the price point this model is aimed at, so could be better, but not deal breaker. Extra Features/Accessories: Another selling point to me was it's RDS capable, another first for the air pistols in my collection, however, I'm also glad to have read the manual about how that plate is mounted to the slide, (screws from the underside of the slide) before attempting to take things apart. I can't give a score on that without trying it, but my criteria would be: what exact what plate/sights it compatible with? AND whether or not that is a proprietary item from Sig. Accuracy: Out of the box I found myself shooting low. I'm not the best shot and it was the first target practice of the year. Excuses aside the groupings looked good, tight enough to have punched a decent hole in the cardstock with just a couple strays. Conclusion: Many things to love about this latest offering from Sig, but certainly not flawless in execution. Very good value for the price point. When I can get my hands on some spare magazines and a RDS I have a feeling it may just become my go-to for day-to-day practice.
