I am a lifelong 1911 fan.
Longslide 1911s are awesome.
I have a Springfield Armory Longslide in 45acp and a Para Longslide in 10mm.
I also have a Para P1640sw that I mounted a Wichita alongside comp on...simulates the weight/balance of a alongside and is ported.
Obviously they are a lil slower from holster, and likely not eligible for most of the Gamey competitions.
They are a thing of beauty, fun to shoot.
Of course here in Canada we are strictly ventilating cardboard so the extra velocity is of no consequence or benefit.
