thingiverse

These are magazine blocks for Sig Sauer P320/P250 compact and full size magazines that serve as a useful means of limiting the number of rounds that can be loaded into a standard capacity magazine. Two versions are available here, each offered in six different heights, both designed to replace the magazine insert attached to the bottom of the magazine spring. One version features a peg that locks securely into place within the magazine base plate just like the standard factory insert does. The other option includes a hole sized to accommodate a 5/32" rivet with a 3/16 - 1/4 inch grip range easily available at any hardware store. Conversion sizes used to achieve a capacity of 10 rounds are as follows: - 9mm Compact magazine, initially holding 15 rounds, can be converted to 30mm to 34mm height. - 9mm Full size magazine, originally designed for 17 rounds, can be modified to a 40mm height. - .40 Full size magazine, initially holding 14 rounds, can be converted to 32mm height. Please ensure that you are aware of your local laws and regulations regarding such modifications.
