I don't have a TH9, but I put a Lakeline in me G3c and it did make a slight difference in the recoil impulse. I also believe it is much better made and will last considerably longer than the factory one. Kept the OEM for a spare. Anyway, they definitely "look" more robust. I can already hear the naysayers saying run the OEM until it breaks. But then you have to wait on a replacement. Not good if it's your edc. Imho💥🔫

 

I don't have a TH9, either, but I did put a Lakeline Recoil Spring Assembly in my late production Taurus PT111 Pro, and the Pistol did seem to operate a bit smoother.
I also believe that the Lakeline RSA is better made and more durable than the Factory OEM RSA.
Like Florida Yankee advised, keep the Factory OEM RSA for a spare.

Btw, my Taurus PT111 Pro is my current EDC.

 

Where do you apply the 'recommended' grease to the Lakeline Stainless Steel Recoil Assembly? I assume where it goes through the opening in the opening in the slide. Is that correct?

 

You are not supposed to have to "lube" the recoil spring assembly. Although a very light application of a gun oil might not hurt. It hasn't hurt the one on me G3c. But no grease.

 

Here is what it says on the Lakeline product description:

Installation Difficulty:

Easy. Lubrication with Gun Grease recommended.

My comment: I assume that since it is metal to metal where the recoil spring assembly meets the slide that maybe some gun grease there?

I emailed Lakeline with the question about where to put gun grease and I received no reply.

 

That is really odd. When I got mine 3 years ago that recommendation was listed. I looked at the assembly instructions that came with mine and it doesn't say it on them either. Guess it's progress.

Well having caused me much consternation, I researched the matter for two hours on a dozen gun manufacturers sights and you tube videos. And I usually read, understand and follow manufacturers directions. And I tend to over lube for the sake of it. But it breaks down thus : 60% say no lube necessary. 40% say lube it. Of the 40%. One says three drops of oil front, rear and center, one says wipe down with slightly oiled rag. One says spray with silicon spray. All say extra cleaning necessary due to build up of combustion products and dust dirt lint et.al. . I go for the molybdenumpolytetrafloroethylene (MPT). OR drop of oil personally. If you wish to grease it do it lightly on the coil springs. No need to overdo it. IMHO💥🔫

 

@TheKid7, don't know if you've ordered the Lakeline springs yet, but here's my two cents worth: My TH9 has 3,500 rounds through it with the factory recoil spring assembly. I have an OEM spare that I bought from ShopTaurus.com, in case the one that's in the gun breaks or gets weak. In fact, I have OEM spares for all my Taurus guns. At the time I bought them they cost between $7.99 and $9.99. Thankfully, never had a factory spring break (knock on wood).

I bought a Lakeline RSA for my G2C. It is extremely well made and certainly nicer looking than the factory spring assembly. However, I could not tell a bit of difference in terms of felt recoil. Ultimately, I reinstalled the factory RSA because I like it better. Can't really explain why, I just do. The Lakeline RSA is sitting in a box in my gun cabinet.🥴

The Lakeline springs are beautifully made. In my estimation, they are a nicety, not a necessity. Between my G2C, GX4, and TH9, I've shot in the neighborhood of 3,500 rounds through each one of them. All have factory recoil spring assemblies. It's your money, if you want the Lakline springs to spruce up your guns, buy 'em...but the OEM springs will likely serve you just as well.

As for lubricating the Lakeline RSA, the literature that came with mine stated to use GREASE where the inner and outer rods slide together. There's a picture included that shows where to apply.

 

I ordered both of them (TH9 & TH9c). I am guessing that they will be here before the end of next week. I hope to be able to give both of them a try within two weeks.

 

I finally installed the Lakeline springs in my TH9 & TH9c. I went the the range and fired more than 50 rounds each (FMJ ammo). As far as I can tell they work great. The new springs feel a lot better than the original springs when I put them back in after cleaning.
