For those looking for 9mm Tokarev conversions out there...after looking high and low, and finally sourcing one, you may find it a bit disappointing.
I happened onto a 9mm barrel and two magazines for my Tokarev last year, then proceeded to buy another TT33 for my conversion.
Long story short, you would need to get a different slide return spring, because, unless you are shooting P+ ammo, it wont cycle properly. Lots of FTE's. I tried all sorts of 9mm ammo, and found that the spent casings would barely clear the ejection port. Most would get caught in the port and jam up the slide.
I bought a used Norc 213 off the EE, and this gun shoots 9mm all day, looks and feels like a TT33. Plus, the gun cost less than the conversion barrel/mag kit.
The 213 uses a different magazines as does the TT33...it matches the length of the 9mm cartridge. The magwell in the 213 has a u-shaped spacer at the rear, in order for these magazines to fit correctly.
The conversion magazines have a u-shaped spacer inside the rear of the standard Tokarev magazine with a modified feed plate and spring, in order to accommodate the shorter 9mm cartridges.
Bottom line? Buy the 213 with as many mags as you can find. You will like the gun much better than messing with the 9 mm conversion barrel and mags.
