Questions regarding 1911 conversion kits

[mav]

Hey folks. I have a couple of questions regarding .22lr conversion kits for a 1911. Back when I had a Kimber Tactical II HD I had bought one of Kimber's .22 conversion kits. The kit fit with no problems whatsoever. The accuracy, however, was something else. Now it may have been me, but I thought the accuracy was pretty sorry.

Long story short, I ended up buying a Ruger Mark III Hunter. The Ruger is incredibly accurate. I have put > 5k rounds through the Ruger and have enjoyed it immensely. With the Ruger in hand, the conversion kit has been setting in its case for about 5 months. On the 1911 side, I got rid of my Kimber, and replaced it with a Wilson CQB and Nighthawk T3.

I went to the range today wanting to use the Kimber conversion kit instead of the Ruger so I could do some specific work. Here's the rub. The conversion kit will not fit either the Wilson CQB or the Nighthawk T3. The fit is so tight that the slide would not move.

Is this to be expected from custom 1911s?

Has anyone used a conversion kit on a Wilson or Nighthawk? If so, who was the manufacturer and how did it perform?

Last question. I have seen kits from Marvell for >$400 that are supposed to have really good accuracy. Before I spend that kind of money on another conversion kit, does anyone know how the accuracy of such a kit would compare to the Ruger I have? If it is anything like my Kimber conversion kit, I think I will just do without. Thanks.

I've never used the conversion slides, but suspect the accuracy will never be as good as your Ruger. Custom 1911's are known for being tight in the slide. The conversion should work fine with any factory stock gun.
