The weighted slide is 1578 RPM which about 400 rds less than the stock 1950 RPM. Congratulations! The ROF is now slow enough to allow a suppressor to be used without the increased back pressure outrunning the mag feed.
TX22 FRTs

It appears that the stock system was running at over 1900 RPM. With the added back pressure of a suppressor, the magazine could not keep up with the ROF. Slowing the slide down with a heavy optic, weights or subsonic ammo slows the ROF enough to use suppressors.
My bet is the -10% spring will allow the slide to run even faster again. The slide could batter the feed ramp or break the slide in the front if there is too much recoil.
The TX22 has a history of battering feed ramps, breaking the front of the slide and non concentric barrel rifling. It's a Taurus.

I just shot a few rounds of subs with the can and no weight. I tried both a very heavy can and my lightest can.
The gun fires, feels to recoil strongly, and then loads another round. The striker has released but doesn’t fire the second round.
The striker resets (*) before it returns far enough to grab the next round (meaning that if it loads a round then the striker had reset)
I believe that the problem is bolt bounce. The added bolt weight could help with that. I’ve dealt with a ton of 22lr bolt bounce over the years. In fast fire guns it’s more a solution of timing the bolt bounce than it is completely solving it
I’ve read enough people online talk about the -10 spring curing their similar problem that I’m willing to try it.
I’ve never had a malf that I thought was the gun outrunning the mag. Which is so surprising given the crazy RPM
* I was going to say “re-cocks” but then I remembered where I am ?

Yes,...22lr burpguns really do need to be open-bolt for that reason of bolt bounce. The most reliable .22 buzzsaw I ever played with was a Marlin Papoose converted to open-bolt. With a bobbed 8 inch barrel and a can on it, it always sounded like someone running a dry chainsaw.
Watch how he keeps looking at the slide between bursts. He knows there's a chance of a miss feed.

I look forward to hearing if it works well. I have one on the way but it’ll be awhile. Let us know please
It’s a test to see if YT sends me to band camp again ?
I put a 20lb recoil spring in the m&p and buffed the disco/frt and it ran 100% today
I tried shooting the tx and m&p on steel. Both were a humbling experience. The m&p is easier to hit with because of the slower cyclic rate.
I consider myself pretty good with MGs and have shot Glock 18s occasionally. These types of guns are an entirely different challenge
They sure are fun! I tried gorilla-ing the tx and started causing malfs

Just a thought, but since the barrel is fixed and the gun is simply blowback, has anyone one with some skills thought of buying a spare slide and using it to extend the slide, making a barrel extension, and making a longer guide rod and spring? I would think with longer slide travel and more mass in the slide, that could make a significantly slower ROF. That would tend to keep the extra mass closer to the center of the recoil force and guide rails. I would think that the slide would be a little too heavy. But you could lighten inside the top of the slide. So as to keep the additional mass closer to the slide rails. I would think that would be easier on the slide rails instead of adding mass to the top of the slide further from the rails. The mass being closer to the rails would tend to reduce the rotational force of the recoiling slide to be easier on the slide rails.
This would not be a 10 minute project. But with the increased travel and the right amount of mass closer to the slide rails, it would seem to me that the cyclic rate could be significantly reduced. Once the R&D was completed, a CNC program to make a complete long slide, threaded barrel, guide rod, and spring could be a popular accessory kit. The current concept looks cool, but this such a high cyclic rate and small mags, the fun seems to end even faster than a Mac style RR in factory configuration.

Got the tx22 frt Tue and I pick up the pistol tomorrow.
Tried picking it up today but no one in true value gun dept to do the phone call.
Strobro same deal for me the frt showed it shipped a week ago last Mon. and showed up Tue. in the mail.
I did get a out for delivery notice on it though.
Try again tomorrow for the pistol.
Replacement slides are only 80 bux and the frt is being reported to cause signifigant wear on them.
For 80 bux I'd consider it a consumable.
I'm going to eventually see if I can fill lthe slide holes with zinc inserts after making a mold.
Should be over kill with the weight since there are three voids.
It will look a lot cleaner too.
Or milling a rear charging handle out of brass on the mill like the Tandemcross HALO charging handle.
Another project for this winter.

I’m not sure if the wear issue is a real issue or not. Pembleton seems to be the one pushing the discussion

Supposedly the sear hits a piece of plastic inside the slide and dents or cuts it over time.
Not sure if it happens fast or if it is like a regular 22 where over time or round count it happens.
Also not sure if it even hurts or affects anything once the frt has worked it's way into the plastic.
Find out soon enough but I'm not to worried about it.
As mentioned only 2 or 3 reports about it and so far no reports of failure from it. And only that one person ( prembelton ) seems to be making it a issue of it.
No FB so I'm going by what other forum posts parrot, they refer back to him with the he said she said.
Between the price of the gun and the price of replacement parts the tx22 is what I consider a dumpster gun.
Wear it out or break it and it is cheaper to toss it in the dumpster and buy a whole new gun over what some replacement parts cost.
