That IS the approach I take. I own a few sentimental/just-because guns but don't use them for training. Every TDA gun I own is a Sig P2XX. Every striker fired gun I own is a Glock (except the Shield, and if Glock had made a gun that size when I bought it, I'd have the Glock). I own a variety of revolvers, but only Rugers have seen any carry. The reason I got into Sigs was I wanted a hammer fired gun and with my crooked fingers the finger grooves on Glocks compromised my grip and rapidly caused blisters. Now that we've went to the Gen 5, my Sigs sit in the safe. I hold on to them because they don't eat anything and I might return to them after retirement.
