I have a P-345 , really like it. It certainly doesn't have the fat grips as some 45s do. However its only a 7 shot mag also. Double stacks are far wider. As far as reliable....it had one malfunction on the first mag ...assume it was a burr or something ? Its never missed a beat since. I've only got maybe 7 or 8 hundred rounds through it...not much, but no signs of wear yet. It will shoot 3-4 inch grps at 25 yds with bullseye and 200 gr XTPs. OMO , but I think you'd have to shoot many ,many rounds through it to wear it out. At their price ,ifin ya do wear it out, buy another one. I've never owned or shot a Glock. (I like hammers)Seems like there's a lot of hype about owning a Glock, kinda like the Model 29 thing after the Dirty Harry movies came out. From what I understand and read, the XD's are great pistols, no experience with them either. Guess I'll stick with my Rugers , To each his own........regards , irold
