Losing the muffin top makes everything easier. Except perhaps winning at see-saw. I suffer from the same problem.BenderRodriguez said:
Love the 34. My 19 is a Gen4 and the grip hasn't ever bothered me too badly, but I know some people really hate it so I get why you prefer the gen 3 grip. And I thought it was interesting that the Glock guys were having as much trouble with magazines as they were. Never seen that before, but never shot a match below freezing before either. The magazines would still eject reliably, but they would stick in the mag well about half way out and need to be stripped out by hand, which slowed them all down a bit. My Dan Wesson was slightly frozen and took a bit of effort to get the slide moving before we shot the first stage, but once we were shooting I had no issues. My reloads are still damnably slow...I got used to the nice big double stack Glock mag well and I fumble my 1911 reloads sometimes....stupid single stack magazine wells are less easy to reload quickly.
I hear you on wanting to use every day gear. If you use kydex IWB holsters I think it'll be no problem. I use a leather IWB for my 1911 and it just isn't easy to reholster over and over again at a match. I've done it once or twice, but much prefer using OWB kydex options...less for the draw and more for the ease of re-holstering.
I also need to lose some muffin top...that would make reholstering easier too.
I use a CrossBreed Supertuck for daily carry. It holsters easy enough. I've used it for some of the training classes I've taken without issue (although it's certainly not as easy or fast as an uncovered kydex IWB holster).
I haven't seen that issue with Glock mags either, but I also haven't spent any time shooting it below freezing.
