Some Examples

Ah, hell, already blew my budget on Christmas but that G21 SF has been on my wish list for a while…and the price is right.
that .38 would be pretty cool
Well, I ordered one…now I need to look into mags…and see what my 45 reloading supplies look like…and probably pick up and aftermarket barrel for threads + cast bullet friendly rifling…see what you started?!
