Shot mine today for the first time. Put 30 rounds through it just to get a feel this morning, flawless. This afternoon my 12-round mags came in (GrabAGun is FAST!). This evening I took it out to my friend's house (yes, I do have one - TWO actually!) and we side-by-side compared it with his Glock 43, which he has been a big fan of.
Right off the bat, I had some problems. We started having immediate problems with FTEs and failure to fully cycle. Had to manually rack the slide with almost every round. WTF??? I was flabbergasted... earlier it was flawless. And yes, I cleaned it this morning and lubed it with Ballistol. My friend commented it felt like the loads may be underpowered. They were from a Dillon ammo box I grabbed off the shelf, about half empty or so. On second look, they were mixed brass FMJ. So we loaded some up in his G43 and it fired it "better" but was still having the same problem. The conclusion we came to was that this was a box I had reloaded during my first attempts last summer I think, and I guess it was all underpowered. WHEW! I didn't label the box.
So... then we opened a new box of Remington JHP bulk. Loaded up the 10-round flush, the 10-round pinky-grip mag and a couple of the 12-rounders... and it functioned FLAWLESSLY from that point forward. So apparently my experimental reloads just weren't allowing it to cycle properly, same with the G43. WHEW!
So we moved on to some direct comparisons. The front of the grip of the G43 is VERY flat. The Sig is slightly more rounded, with a little bit of a finger groove just under the trigger guard and is slightly undercut. We both concluded this was incredibly more comfortable to shoot than the G43. And keep in mind, he's been a big fan of his little Glock. But he's an open-minded sort, so he agreed.
Also, surprisingly, the flush-fit mags did not Significantly affect the shootability or accuracy of the Sig as compared to using the 10-round with the pinky extension or the 12-round mags. Then we tried a few runs with rapid mag change from the flush to the 12-round, and though it seemed to feel just fine and shoot just fine for us with both, swapping to the 12-round mag did seem to allow both of us to get a very minimal improvement in follow up shots, getting back on target a tiny bit easier. Overall, the flush mag doesn't seem to be a detriment of any consequence in shootability. I was very pleased with this.
The only problem I had (so did my friend) was trying to do mag drops for swapping the mags, not a problem with the gun itself, but precisely because it is so small, you really have to unravel your fingers from the bottom of the grip in order to get the mag to drop free. Basically ended up really extending out the pinky (as if you are drinking hot tea with your pinky extended) to clear the mag to get it to drop free. Just something to get used to, not any kind of malfunction, just training with this firearm.
Overall... incredibly INCREDIBLY impressed with this subcompact. Both of us. He is planning on picking one up, as well, probably in a few months, as he just bought an RDB. But he agreed it was much more "pointable" and more comfortable to shoot than his G43. Once we compared the 2 in the hand, that flat frontstrap of the Glock made it much less comfortable to shoot. Neither of us have small hands. But the thing that most impressed and surprised me overall was how even with the flush mag, it didn't really affect the feel or shootability of the gun in a negative way. And carrying 4 extra rounds in a stock mag is crazy good, in a gun with a marginally wider grip and smaller in pretty much every other way is just shocking.
Some early problems seem to have been mostly resolved with Sig's changes, and I think they just flat knocked this one out of the park, overall. I think my wife and 12 y/o son are probably going to really love this gun, and I may have to buy another one or two in order to keep mine in my own hands!
TL;DR - great gun, much preferred over the Glock 43 for me, and my friend who carries the G43 every day.
