This is a must have item if you hate the square uncomfortable grip on your standard gun.This two piece wrap around grip will make shooting a lot more comfortable and easier for longer periods of time. It does not replace stock grip but slides over it without making any permanent alterations. Works well with or without our quick drop magazine release lever for the M-11 with Sten conversion. If you are tired of the original square shaped hand grip then this is the remedy for you. (grip only, other components sold separately) This grip does not have the straight sides and has the expansion slots on both sides for the magazine ribs. Fits all Master Piece Arms 9mm guns, 30, 30T, 35, 35SST, & 20SST mid sized MPA 9mm guns & Mini 930. If you are using the NEW Tapco Magazines, the mag or grip edge may need to be trimmed to fit. Please see other part number for Mini pistol grip.
