Wow this upgrade spring made difference in my P-11. Thank you for producing a great upgrade spring & the step by step videos.
I have shot the gun with the Mcarbo springs yet, but they seem to be high quality.
Seems to help. Less snap in combo witht the SS rod.
I ordered the following parts for the PF-9 on April 29: 20 pound recoil spring Trigger spring kit Flat trigger SS guide rod Textured grips Bench block Due to unavailability of parts, these parts didn't arrive until Jun 13. All of the parts were installed at one sitting as I didn't want to disassemble the gun more than one time. Following the videos on the MCARBO website, the parts were installed without any problems and the changes in the gun's operation were very noticeable and made the PF-9 much more enjoyable to shoot. The process was easy and enjoyable, but patience and a little mechanical skill are required as some of the parts are very small and reassembly does take a little dexterity and finesse. However, the parts are well made, fit like a glove, and are well worth the time and expense to install on your PF-9. They will definitely improve the weapon.
Both parts did the trick. I fired numerous loaded magazines and no more jamming. The correct parts were ordered and received within four days. Thanks you M-Carbo for the great products and speedy service. Other industries could learn a few good skills from you! David M.
Could not reliably operate slide on KeltecPF-9 so replaced stock with M*CARBO 20lb Spring and Stainless Steel Guide Rod and now it works perfectly. Thanks M*CARBO.
The best springs are made by M*carbo will buy again.
A performance and function improvement when matched with the stainless steel guide rod.
Installed in my P11 without any trouble. Waiting to hit the range to see how it goes.
I installed the 20lb Max Control recoil spring along with a stainless guide rod (I had already installed the trigger/action spring kit). I honestly felt like I had switched from 9mm to .380. I was shooting a fairly stout load too - 121 gn Lead cast, 2/10 gn below max load. Going to have to try the CZ 75 P-07 kit next!
Installed this with the stainless guide rode and trigger and hammer springs. Works very well as a set. Fast shipping and good product.
I Installed this item along with the Stainless Steel Guide Rod. The felt recoil was reduced drastically, and the weapon is much easier to control. Great product, and service.
I installed this spring set with the stainless steel guide pin. Took it to the range and put about 100 rounds through it. I like the performance.
Fast shipping and worked great with the MCARBO Guide Rod
What a difference this upgrade made. Add it to the guide rod, trigger spring and new trigger and you be extremely happy with the new performance.
Installed in less than a minute. Looks great. Have not gone to the range yet for testing. I feel much more confident with the S/S OR than the plastic one.
