Product Description
Rock Island users have asked us for a custom basepad to match our "Fattie" magwell ever since we brought it out. This is that basepad. (Also works on Para-Ordnance P-16 and P-18.)
- +4 capacity in 9mm or .38 Super (+2+ in .40 or 10mm) for 21+1 and sometimes 22+1 performance!
- Can be used on a .45 -- just remove the plastic insert, or trim the "legs" of the insert.
- Legal for USPSA, 3-Gun competition (meets the 140mm rule)
- Works with TF "Fattie" magwell and RIA factory magwell.
- Uses the stock spring.
- Includes modified Arredondo Accessories insert for jam-free function beyond 18 rounds
Note: Works with Mec-Gar Para mags, and with Rock Island mags. HOWEVER, Rock Island recently started offering magazines that are slightly longer than prior generations (notably in .40). If you are shooting USPSA events, be sure to measure your assembled mags to be sure they fit the USPSA gauge!
Weight: 1.75 ounces
Material: Aluminum
Color: Black
Note: Does not fit the Rock Island 5.0
NOTE: Due to state department restrictions we cannot ship this part internationally.

TF Fatty +4 basepad
They are awesome, but they were designed to be used with a cut frame para ordinance, ria or metro arms American classic. Using a p18 mag with the TF fatty TALL speedwell with the basepads have to be shaved down to the point of useless to work. Found Remington 9mm magazines work with no shaving, however they fall slightly out of 140mm range. For that reason only 4 stars. None of this information is available anywhere and only a few people know this is you're lucky enough to find one. REPSONS: Lawrence, that's why we make 140mm extensions for the Remington magazines. Sounds like we need to do a better job advertising that!
