$$$!
I would get the G21 and buy the conversion barrel for 10mm, that way you have
two guns in one. 45acp is so much cheaper and abundant to practice with. I’ve
done this with my G30.
I thought about that. I reload and decided to the the G20 and buy a 40 S&W barrel for cheap practice ammo.
45 auto ammo and component are getting pretty expensive. I have a friend at the police range that is supposed to bring me a bag of 40 brass. I haven’t seen free 45 brass in ages.
Although I have to admit, I’d like the idea of a 45/10 combo over a 10/40 combo.
