Hi All, I'd like to introduce my company for those that don't know me yet. We are Jager Products Inc., and we manufacture guide rods and compensators for Glock pistols. Our guide rods are CNC machined from steel, hardened and black oxide coated for those who prefer to keep the color of the guide rod black. These are available for all models except the sub-compacts. For the G34/G35 length slides, we also offer the "Heavy Extended" model guide rod in the larger .270 diameter designed for Wolff recoil springs. We also are the only manufacturers of Polymer guide rods, and these are the only guide rods to be ruled legal in SSP division for IDPA competitors. These are for the G17 sized frames. Remember to check compatibility, the G17 size frame is used for the G17, G17L, G22, G31, G34, G35, G37 and all use the same guide rod. By installing an aftermarket guide rod, you'll have the ability to change recoil spring weights according to your caliber and load since all these models an calibers come from the factory with the SAME weight recoil spring. As an Open Division competitor in IPSC / USPSA myself, we designed a compensator that is not only the most effective on the market but also aesthetically pleasing. Check out our website, we have secure online ordering and continually add new products. In about a week we will be adding our Open Division / GSSF package to the site, which consists of a threaded barrel and compensator, JP Enterprises red dot sight and adapter base, guide rod and recoil spring. Convert your stock G17 to GSSF Unlimited division compensated dot gun in a few minutes with no permanent modifications to your firearm. In stock now, but working on the website. Thanks, jager Wanna kill these ads? We can help!
