muncie21 Posted August 2, 2017 Share Posted August 2, 2017 My 9mm pistols typically throw the brass about 8-10' from me, at the 4/5 O'clock position. My .40 TSO on the other hand seems to throw the brass 10-18', when shooting a 172 PF, 180gr bullet. I've tried 14, 16 and 18 lb springs in addition to the 13# (I believe, the pistol was used) spring to test for functionality. All of those springs will cycle a full magazine with no malfunctions, tested with ~20 rounds per spring. I didn't spend enough time with the heavier springs to determine how they impact follow-up shots and overall fit with my grip/style. Looking for feedback on what some other folks are using and why.

reballz Posted August 2, 2017 Share Posted August 2, 2017 I have whatever is Factory.... does anyone know what that is? Link to comment Share on other sites More sharing options...
aandabooks Posted August 2, 2017 Share Posted August 2, 2017 13# in mine with 200gr 172 PF loads. Throws brass 6-8ft. Link to comment Share on other sites More sharing options...
zzt Posted August 3, 2017 Share Posted August 3, 2017 (edited) #14 is factory. I use a 13lb spring for loads between 140PF and 172PF. At 172, brass is tossed about 6'. The 140 just dribbles out at 2'. For sub-minor loads for SC I use a 10 lb spring (135gr at 115-120ish). Edited August 3, 2017 by zzt Link to comment Share on other sites More sharing options...
Ck867 Posted August 3, 2017 Share Posted August 3, 2017 What springs are people using and are you using the buffer? I just put 100 rounds through mine last week for the first time so no time to experiment with different springs yet. Link to comment Share on other sites More sharing options...
zzt Posted August 3, 2017 Share Posted August 3, 2017 No buffers. They were put in for the IPSC version that had slide stop breaking problems. When they transitioned to the TS, they were included, but not necessary. When I bought my TS from CZC, Stuart told be never to use them. Link to comment Share on other sites More sharing options...
muncie21 Posted August 3, 2017 Author Share Posted August 3, 2017 BTW, I run mine with no buffer installed. Link to comment Share on other sites More sharing options...
stuey93 Posted August 5, 2017 Share Posted August 5, 2017 What is the most recoil friendly load/recoil spring combo you guys can get to run in your TS/TSO Link to comment Share on other sites More sharing options...
obsessiveshooter Posted August 6, 2017 Share Posted August 6, 2017 My TS has a 10lb recoil spring, 13lb mainspring. 169PF loads, 180gr BBI over titegroup. It might be hard on the gun but the sights settle quickly where I want them. No buffers. Sent from my SM-N910V using Tapatalk Link to comment Share on other sites More sharing options...

Just teasing Interested to see if there is any correlation between low recoil spring weight and broken parts. I think a 10lb recoil spring isn't too uncommon among major PF Limited shooters, especially with glock and 2011s.I haven't broken anything yet, but I've only put about 3k through mine.

aandabooks Posted August 6, 2017 Share Posted August 6, 2017 10lb seems a little to light for major loads. With a 13lb in mine is throwing brass about 6ft. Link to comment Share on other sites More sharing options...

All CZ's break slide stop's. CM is major and using a 10 lb recoil spring so it should also work fine in regular TS .40. Link to comment Share on other sites More sharing options...

FlightMedic376 Posted August 15, 2017 Share Posted August 15, 2017 I run a #15 hammer and a #13 recoil spring. 170pf ammo is throwing brass 6-8 feet away. Link to comment Share on other sites More sharing options...
obsessiveshooter Posted August 17, 2017 Share Posted August 17, 2017 I choose my recoil spring weight by judging how the sights settle. It's a given that the brass will eject, and I don't care how far as long as in doesn't hit me in the face. Too heavy of a recoil spring seems to cause the front sight to drop as the slide slams forward. I'm sure running a light recoil spring will reduce the life of the pistol. I but I want to shoot the next shot sooner, more than I want the gun to last forever. Just my opinion, it's a subjective thing.

pistolshot Posted August 23, 2017 Share Posted August 23, 2017 I have a 11 LBS and shoot major at around 174 PF with no buffer. No issues that I can see. Link to comment Share on other sites More sharing options...
kaibabcowboy Posted August 28, 2017 Share Posted August 28, 2017 (edited) I purchased a TSO, have about 800 rounds thru it. Using 180gr at 165-170 power factor. I need to know how to determine what spring(s) are best for me. Oh, and how do I determine the weight of the springs that were included with the gun?

Why put them on a scale of course Now obtaining the spring weight, that's a bit more problematic. All teasing aside, I 'believe' that factory Tactical Sports' shipped with 14# springs. I'm sure there's enough talent on this site, that someone will be able to confirm this is accurate or not. Some folks count spring coils, however I'm not sure how accurate this method is.
