I am hoping to buy a 9mm Glock 19 Gen 4 someday.
How do I know when the time is right so that it will have the right recoil spring in it from the factory?
When buying ammo for it, what power factor should the ammo compute to, for good operation?
I noted using 124 gr. bullets for the break in.
How many rounds should be considered a break in for the gun?
Thanks much.
