Two different TX22's, an early one and the later Gen 2 non TORO. Both were shot only suppressed with CMMG Zeroed 22 and/or Dead Air Mask. Both gave slow mag feed jams. Magazine cleaning, tuning and various lubes did not help. Jams happened in both the long and short magazine, 1 to 3 per magazine, mostly around half way through the mag. The Reason: suppressed gives more back pressure than non-suppressed, this causes slide velocity and cyclic rate that is too high for the feed speed of the magazines. YouTube FRT videos confirm extremely high cyclic rate. Test: Hybrid 46 suppressor has far more volume and far less back pressure than a 22 can, so I used one. Permatex 3000 deg F ceramic brake grease has high viscosity, it was used on the frame to slide tabs, in the slide grooves, in the recoil spring assembly, on the slide face and a bit in the short mag that was used. High viscosity grease was used to give extra friction to slide cycling. Sparing use of this grease in the mag was done to reduce cartridge rim friction and this grease resists hot gas and debris blowback. A long mag spring was used in the short mag to increase the magazine spring force. Remington Standard Velocity and Rem Golden Bullet Hollow Point ammo was used, 15 or 16 rds in the short magazine. Result: no more fail to feed, slow mag, jams. Out of 61 rounds fired, there were two light strikes caused by almost but not quite in battery and one out of battery that required the slide to be pushed forward. Otherwise the TX22 was now reliable suppressed. Changing to a huge suppressor having far less back pressure worked. Remedy: not done but needed, stiffer magazine green springs, a 2.0 oz slide back plate weight, stiffer recoil springs. This should fix the too high cyclic rate problem and the occasional out of battery problem too. After these things, I'm hoping that 22 cans will work on the TX22. Note: The TX22 is extremely easy to shoot well and to get good hits with. Sighting using a Baldr S green laser is far easier than using conventional sights or dot sights, for me anyway. Hope this helps somebody. Fast slide, slow magazine feed problems continued after posting the above. Using longer and stiffer green magazine springs did not help. Standard velocity ammo only helped a bit. I changed back to stock mag springs. All shooting was done with a suppressor. Tried a 3D printed, plastic, box style back plate, weighted with enough lead to bring the weight up to 2.0 oz. It worked for 3 shots using Rem Golden Bullet HP's, then the bottom sheared off from the top and dropped the weights. Next I used strong strapping tape and epoxy to keep the bottom attached and used lead weights to bring the weight up to 1.85 oz. 20 shots from the long mag worked perfectly, so did 8 shots from the short mag, then the ears holding this 3D back plate to the slide sheared off. But, weight on the back of the slide was proven to work. Note, this 3D printed slide backing plate box, from eBay, was beautifully made, but revealed that plastic is not the correct material for the sudden loads involved. Change of momentum divided by change of time equals force. Larger momentum change or shorter delta time causes larger force. Atlas Tactical makes a stainless steel 2.0 oz back plate for the TX-22 slide, I ordered one in black color. After a few days it arrived and is simply beautiful. It is smaller than expected and is not very noticeable on the TX-22. Off to the range, 40 rds from the long magazine and 30 from the short magazine ran perfectly. Ammo was Remington Golden Bullet HP. Suppressor was Dead Air Mask, laser light was O-Sight Baldr S green. Because the suppressor screws directly on to the barrel, without an adapter, suppressor walk off was very slight and a twist on every magazine was enough to avoid baffle strike problems. My shooting with the factory sights was only fair. Then I used the Baldr S green laser for sighting, the results were spectacular good. This TX-22 Gen 2 non-TORO is very easy to shoot well. Note: you can shoot a lot of shots pretty fast with a TX-22, suppressor heating is substantial, more so than the same number of rounds with a rifle. Fortunately it takes a while to reload the magazines. Slide locked back, suppressor hanging out in the breeze helps some. The supplied magazine loading tool, a lot like a Glock mag load tool, works very well. But, it's good to have a couple more guns to shoot while the suppressor cools. Atlas has fantastic videos on YouTube that show how this weighted back plate is made. After watching these, the price point is very well understood. Another solution: TX-22 Gen 2 TORO model needs 2.3 oz to run well, Atlas makes a 2.3 slide weight. There are heavy optic sights that might be heavy enough to cause the TORO model to cycle without problem, without weighted back plate. Or, maybe, use a 2.0 back plate and a very light optic. Recoil? Trigger pull? Didn't notice. Holes in the target? Big smile. |

Tx22 manual says not to use -high velocity- ammo suppressed. I tried heavier spring rates, did not help. With subsonic type ammo, zero issues over thousands of rounds suppressed. With any high velocity type ammo, have multiple issues per magazine shooting suppressed. Unsuppressed, have zero issues with the same high velocity ammo that chokes when suppressed. It took a relative telling me about the information in the tx22 manual. I wish I would have read it sooner… |
