Magpul ten round mag modified to hold five???

[jluck]

Today I got a short ten round Gen3 P-mag and a five limiter, Cut .600 off limiter and put it all together. Five rounds fit with no excessive friction or binding nor does the mag swell. The mag easily slips in and out of the magwell. I will function test it soon and report. The only drawback I see and it is huge to long loaders I'm sure is factory Hornady 123 grain ammo is a tight fit almost rubbing the front of the mag. I don't see anything longer than about 2.250 fitting.
