Help Me with 10mm. Some Questions??

[oldman10mm]

I've got plenty of 10mm mags I could modify for the conversion IF it would work. I've only got a few 4013 mags, so I didn't want to convert them if some 10mm 'donor' mags could be used instead. That's why I asked.

In todays' market, 1 10mm magazine is equal the value of 2 4013 magazines.

I converted my 4053 to 10mm several years ago. I was fortunate enough to locate an extra slide and barrel for the conversion.
Fortunately, all the 10mm full size magazines I purchased for the pistol after the conversion function perfectly in the gun.
