SW Shield in .45
Price range? Preference for striker or hammer?
.Everything now is polymer, striker fired and costs with $50 of the next model. I learned on INGO only old dudes like low capacity metal guns with hammers and big honking bullets
.
OP says he's 66, so he can be in the old dude club if he wants to be.
If I wanted a striker fired, I'd look at the Glock 36. On the hammer side, the P220 Compact/P245 from Sig. The second is definitely more money.
