I was poster # 3...
I have a real Remington Rand which is a Colt clone of your colt clone, only mine is a lot older. WW-2 Vintage.
I also have a Kimber CDP Pro II probably with the very same Novak night sites you are looking at since that is a good part of the much more money a Kimber costs.
Well the Kimber is a tad fussy about what it eats, which is pretty much either ball (copper clad round nose slugs, or flyin ashtrays, which are reloads really with that style of hollow point)
Now that old battle vetran gun will shoot anything, and I mean anything. It will feed flat nose full blown wad cutters, semi wad cutters too which are tapered at least..
The gun you have is one you will regret selling as it is a high quailty base that works as is, and is the platform all the so called custom guns, which one were real custom guns have become as Les Baer, Wilson, and Kimber which isn't really custom at all. Kimber is a sort of low end custom more factory regular than a real custom, and as such tends to have issues.. Mine did.
Now because it had issue there is always that thinking in the back if my mind..
Since the Rand never did, it is the first one I will pick up on a bad day...
These guys are telling it straight.. Send the slide to Novak, and get the sites... The when you have more if you want get a better trigger for targets, then maybe tighten the rails and get a new barrel. It is still possible to build a gun and better than what Kimber pumps out the door all screwed up.
Wilson makes great parts and will sell them to anyone. You can add improvement after improvement to about 4 grand and still not be out...
If you did that very thing you would end up with a gun that does one job well and not many other jobs well at all. As it is now it will do any job you ask it to, just not as well in a special job..
Good target guns make for lousey self defence guns.
