Tuning Triple-K and/or Colt Steel .22 Conversion Magazines

Anyone have a measurements/dimensions and/or tips on how to tune magazines to work with Marvel, Nelson, and similar conversions?

David sams makes a tool. It has the front and rear dimesons engraved on it. As well as being those engraved sized

I have no measurements, but here are pictures

L>R Colt, Metalform fixed, Metalform before fix.  Colt and fixed work perfectly


L>R  Colt, MF fixed, MF in progress, MF unfixed

i see original colts on ebay with removable base.

KC has a bunch of factory Colt Ace mags (with removable bases) for sale at perry. I picked up a few.  Went to Nelson and we found out they don't exactly work with the slide stop they make.

I’ve noticed on lock back slides that the follower is only pushing slide stop about half way into the slide notch with steel mags: Colt and Triple K. It can cause premature wear on the slide. I don’t lock back any of my conversions. The Triple K mags are rough in comparison to the Colt mags. Lots of clean up work during fitting.

The biggest issue is that the slide stop for the nelson can wedge between the follower and the mag body

Is possible mr Nelson made in a future one slide stop friendly with colt ace mags.

The Metalform conversion mags I have all have rather wimpy ledges to engage the stop piece stickout part.  But that is the design to fit the mag body.

Someone should make a universal conversion slide stop with a trim to fit finger.

Doubt it, they have mags made for their units that run flawlessly. When they make steel baseplates I’ll go back to them

I use/like their magazines but the baseplates cheapen the looks of a fine product.

I also have a lot of different grips that won't work with a Nelson mag because of the oversize baseplate.

I wish they were flawless with my unit.  I get severe bullet shaving with all five of my Nelson mags.  (and yes, I have a call into Larry)

The first two colt mags was modified for non lockback
this others in original factory condition,possibly will work with lockback marvel version.
