I've had a twisted and Z'd Luger extension back in the 80's...Took a long time to get it straight...Months, maybe even a year...Nudging it a bit more every couple days...When I was done, It was straight again, and I looked at it and proudly said...

















NEVER AGAIN!!!

Box yours up and ship it off to Gerry Tomek.

I measured with calipers and it's more like 3/32", 0.095" to be exact. You can't really see it in the picture, but the right rail is bent pretty bad.

The left rail appears to be straight, so I was thinking along the same lines as GT: Clamp it in some kind of fixture, then bend it a tad over to allow for springback. What I had in mind was to clamp the left rail to a straight surface, and also clamp the chamber really tight to make sure that the left rail won't bend. The next step would be to fabricate a small machinist's jack, set up a dial indicator and start spreading it about 1" or so behind the chamber. Spread it a bit, take a reading, check the result, spread a bit more, take a reading, rinse and repeat until it's straight. A slight "Z" won't bother me all that much, this will be refinished anyway so I'd rather file/polish the last few 1/1000 than working it until it cracks.

Then again: I might chicken out and I need for someone to remove the barrel as well, so are you up to the challenge, GT?
