i am going to catch hell for this.
I like the pm7, i shoot mine all the time. If i was going to buy a new target I would want the following changes
6" barrel, yep i would want a pm7 long slide.
Nice tight front strap checkering
a frame fitted for 3 slide pistol pack
1 in 22lr, one in 38 super, one in 45acp.
That is what i would want. the rest could be the same.
in all seriousness, why not you have multi barrel kits for
s, sigs, shotguns. the 1911 is a great platform for a target bullseye set up, with three hand fitted slides. Yeah i know bucko money, yet, well worth it.
