CMMG is releasing a radial delayed blow back AR9 that is now compatible with colt mags; i would give that a serious consider.

Greetings to another fellow hoosier.

we have found mbx magazine springs to be pretty flimsy. Our last batch started having feeding problems on the last few rounds after only a few weeks. We bent some tti springs to fit the mbx followers, and have found those to resolve the problem.
Depending on the gun, short rounds, weak mag springs, and STI gen 2 magazines may cause problems. stronger springs and loading longer may help. And of course loading your own ammo is drastically cheaper than buying 40 ammo.
I've found this to be true on the MBX mags as well; i dont know how many generations that the mbx mags have been through but i have had to replace the older gen mbx with a grams spring and follower kit. Since replacing them with the grams kit everything has been fine.

I’m showing factory loads out of my 40 cal STI/ McCormick gun. What weight spring would be best for me. Thanks
How fast are the factory rounds moving?
I'm shooting 180gr at ~950fps and using a 12# spring with my 2011.

Honcho, BUL, Atlas, and other companies have models that feature a sight block with a 5 to 5.5 inch barrel and a commander-ish length slide.
SVI does not offer a comparable setup however they will do a 5.4 with an island barrel and to-order length dust covers.
Is there a reason they don't do a sight block? How would a 5.4 with an island & full dust cover vs. a sight-block feel? Just wondering if there are good arguments to be made for each or are they basically the same?
I'm not sure why SVI doesn't offer a sight block gun but the sight block is nice to have because it acts as a weight to help eat the recoil. I dont know how much weight fitting an island barrel to a slide would take off of the slide as compared to a sight block gun but i would be interested if anyone has any comparisons.
I have a 2011 on the way right now thats fitted for a sight block and the tri-topped slide weights 9.7oz.

Thats super bizarre, can you post pictures of the parts? Im really curious to see.

I personally prefer to have green FO front post. I shoot a lot at indoor ranges and the lighting can really wash out all black because of the range's dark backstop.
I have tried both larger (1.5mm) and small diameter (1mm) FOs and definitely prefer the small diameter; with the 1.5mm i find is too easy to misread and will cause me to misplace shots.

i need some AR magazine springs.
For action springs I have had good luck with CS springs from sprinco and flatwire springs from Tubbs. So I checked both of their sites for springs and found both make a 17-7 flatwire magazine spring. I actually like the fact that Tubbs says it *can* hold more rounds in a magazine. I'm thinking that would make it easier to load a full 30 round mag on a closed bolt - something that might be very useful in competition.
Sprinco does cryogenic treatment on their flatwire magazine spring and tubbs doesn't. I can't find any definitive information on what exactly the advantages of cryo treatment would be on a magazine spring other than longevity ... but I don't think I could ever load and empty a magazine enough to wear out a regular 17-7 spring.
Does anyone know if there are additional advantages (or claimed advantages) of cryo treatment of springs?
If cryo treatment would aid in preventing spring fatigue of a constantly compressed mag spring I could see that as an advantage ...
I've had a hard time figuring out information about this topic too; a lot of the information seems to be from industry websites trying to hype up their product which makes me less inclined to believe their claims. I know that LMT cryo-treats their barrels for all of their AR's.

The most I can load my TSO mags to are 1.16 without having them hit the mag tubes; I tried 1.17 and I had issues with them feeding.

im interesting in seeing the data for this as well.
edit: this might help you:

Greetings everyone,
I recently found a deal on a used Tanfoglio witness chambered in 38 super imported in 1993. The gun needs a lot of work as it looks like bubba got his hands on it. I'd like to bring it up-to-date but I don't know what exactly is stock on this and what was an "enhancement" to the previous owner. I'm hoping this turns into a fun project gun.
Here are my questions about this old witness:
1. Did the frame come drilled for the optic mount when this was imported?
2. Is the compensator a custom job or was this a model that widely offered?
3. There is a serious amount of play between the comp, slide, and guide rod. What would it take to fix this?
4. Is there any vendors that offer new 38 super barrels?
Thanks everyone!

I believe there was a polymer trigger and guide rod on the older models, someone correct me if im wrong.

Im not sure if others have had this problem but the rear sight adjustment screw's threads just got stripped off.
I started
Thankfully cz's support is great and I spoke to them about this over the phone and they're replacing it. I told them that i had been playing with different recoil springs and took the buffer off; they said that it was unlikely that the recoil could have done it but I don't know what else it could have been.
What sights does everyone else use? im thinking of switching to a fixed rear sight after this.

I use the buffers in my TSO but not in my S2, I have changed them when they start looking beat.
do you feel like it makes any difference? im very new to uspsa and gun tuning and im curious to what other's experiences are with the buffers.

I’d like to know how many people use the recoil buffer?
Mine was starting to fail, so I removed it and have been running without one since. Cajun gunworks recommends not running the buffer...little benefit for the risk of failing or short stroking the slide.
I took mine out on my 40.
Cajun recommends against buffers; they reason that while the buffer wears and tears that the material from the buffer will eventually work its way into obstructing the trigger mechanisms.

They have this listed under their parts for a TSO so im curious how much fitting, if at all, it would take to get it on a TSO.
NROI states a rules clarification is coming re: magnets, flashlights

I honestly think that moves like these are to make uspsa more appealing to the timmy crowd considering the rise in popularity in events like the "tactical games". To the wider gun owner community event like the tactical games are sexy looking with the battle belts and plate carriers and I fear that uspsa will decline in popularity compared to events that are "crossfit with guns".
