Product Description
- MUCH wider reloading funnel
- More than twice as deep as the factory part
- Increases effective frame length, giving your support hand better control
- Aluminum construction = light weight -- Protects mag release when set on a table.
NOTE: EXPECT MINOR FITTING: In developing this part, we noticed wide variations from Rock Island pistols -- the frames vary by up to .050" in length, and the frame isn't always cleanly finished where the magwell attaches. Some minor fitting will be required on some guns -- others will drop in effortlessly.
NOTE 2: This magwell is intended for pistols manufactured BEFORE August 5. 2021. Pistols with serial number RIA2414696 or higher will accept this magwell, but will have problems getting TF basepads to fit. (Look for a modified TF version that works with the new "9 degree" guns in coming months.)
IMPORTANT: Rock Island guns that ship from the factory with a magwell have their grip frames (and grips) cut short at the factory by ABOUT .175". If your pistol didn't come from the factory with a magwell, this part won't fit! However, it is an easy job for a gunsmith to cut your frame back -- at which point our magwell will go on effortlessly.
The reason for the two frame sizes is the magazine. Standard RIA guns use the folded-steel basepad as an overpenetration stop for the magazine (the Browning Hi-Power does the same thing). If you change the folded-steel basepad out for a machined RIA +2, or one of our +4 extensions, the thicker-built basepad will hit the frame and keep it from locking in. Conversely, if we cut an aluminum basepad thin enough to fit in a space designed for steel, the thin aluminum will soon bend and break.
If you have a "long frame" magwell, we have a magwell for that as well, but it requires non-RIA magazines (Remington, MBX, or modified STI).
