STI 9/38 140 mm magazines. Blocked to 10. Perfect complement to your open division blaster without breaking the bank. These are the new style magazines from STI, and unlike their previous abortions, work perfectly without modifying them, even with 9 major.
Supplied with a pretty durable plastic basepad, which won't crack or dent like aluminum ones.
I like these mags.
Made in the USA.
