That is why I have a Novak cut slide. I started with a military match slide, to get a cross dovetail front but a Novak Competition sight in the GI rear dovetail. Cutter broke and ripped out the front dovetail, so the 'smith replaced the slide. I don't know if he thought a Novak rear would soothe my feelings, or if that is just what Caspian had in stock for rush delivery.Someone needs to know exactly what they are doing so the sight fits properly or they will be buying someone a new $300.00 slide.
Don't forget that you can get a brand new Caspian slide with whatever sight cuts you want in it for a whole lot less than $400 from Brownells.
If you're not attached to your slide, buy a replacement slide and any other parts and then sell your old ones off when you're done.
Depends on what you pay for the new parts and what you end up getting out of the old ones. Everytime I've done it, it's almost always been a wash, or very close to a wash, for me. Maybe I'm just lucky, but I've had more than a few Caspian slides drop right onto Springfield frames with no fitting required. There's Kart ezfit barrel options and fitting a bushing isn't exactly rocket science. Anyway, maybe not the perfect option for everyone, but an option nonetheless.Then you have to fit a the new slide to your frame, bushing, barrel. Not real economic either.
