Earlier this afternoon I started a dry fire session. While doing so I noticed along the side of my trigger finger a callus. There’s only one way the skin in that area could be callused: it’s rubbing the frame. I hypothesized it, and I think the callus is pretty good supporting evidence. So yes, if the M&P gives me enough clearance for my fingers, good sign.
I looked at the S&W website a bit. One thing I have mixed emotions on? The magazine release button. It’s reversible, but technically only one-sided. Sure, 99% of my work is my right thumb pressing the left-side button on my XD. Due to the way my fingers wrap around the gun? My left index finger can come in contact with the right-side button… and I have dropped mags. So in a way, to lose the ambi-release is good. But it’s also bad in case I might need it, say in one-handed reloading situations. So, mixed emotions here, but I think the loss will generally be an improvement.
I’m just thinking more and more about switching to the M&P. It’s just fine details at this point. I intend to shoot an M&P again soon to look further into these things.
