10# round wire spring primarily for non captured guide rods in small frame Glocks ie.. G17,G34, G35, G24, Works with most SJC built polymer frame pistols and the SJC 4th to 3rd gen convertion kits for small frame Glocks.

It made my G-17 Gen 4 with 11 port comp. work at 100% with factory 115s.. Installation is awkward and it would be easier if it was a cop turned setup but at least by Glock runs like it should. A very good buy.
Already reviewed the guide rod but this adds versatility to my build and allows me to change weights quickly and easily.
