I’ve been playing w my G45 in CO and I feel I can make faster follow up shots (inside 20-25 yds) than w my 34. The longer side radius of the 34 definitely comes into play but once you put a dot on it, non issue. Shooting the G45 at 40 yds w a dot and easily keeping the in the A zone, I think it’s accurate enough.
the 34 in CO made the gun and recoil feel a little sluggish and slower. G45 felt more responsive. Have t tried the G17, but that will be the next test to play with.
Factory ammo out of the G 45 is 138 pf and up. Non issue
