Wow, I didn't know my little post would start up such a ruckus.
From the looks of things, I'd say most of you really like interchangeable backstraps. Market forces and all that. A couple of responses, if I may:
1.
The 1911. Admittedly, my knowledge of the platform is limited. But I was under the (I guess mistaken) impression that the frame was a single piece of cast or forged metal. I know you can accessorize a 1911 to the hilt with grip panels/rubber Hogue-style grips, beavertails, extended grip safeties, larger thumb safeties, different slide stops, etc, I just wasn't aware of a removable panel in the backstrap in the same manner as the polymer guns that I mentioned.
2.
I'm not anti-customization. I guess I'm operating from my own biases based on being the "average joe" that a lot of the fixed grip guns were designed to fit. I wonder about the longevity and durability of the backstraps, which is probably unfounded because I know there are M&Ps with tens of thousands of trouble free rounds through them.
3.
Mostly, I'm just worried that what I like in ploly guns is going away. When the Gen 4 Glocks came out there was "internet consensus" that the Gen 3s were going to stay around alongside. Well, at least in my Texas location which has a large number of gun shops (both small indys and big chains) the Gen 3s are disappearing from shelves and don't seem to be being replenished. Granted, my G17 isn't going anywhere anytime soon, and works like a dream after 12,000 rounds, but I'm skeptical that Gen 3s aren't going the way of the dodo. Maybe it's just me, but this longtime Glock fan HATES the new texturing more than anything.
Oh well, I like what I have and Springfield doesn't seem to be in any hurry to get rid of their classic XDs, so I guess all is well.
Pleasant shooting.
