Looks like the steel target I ordered on July 24th could be delivered tomorrow!! AR500 3/8" 66% IPSC target. If it comes in tomorrow I might get to shoot it Sunday. Otherwise it will be delivered Monday and I'll shoot it next weekend.

Thanks for the post. Wolf sells the springs in 1 pound increments so you can custom tailor to different handloads. I think Dillon has them listed in their catalog. Looks to be working just fine.

When I went inspecting used 1911's everyone had more wear on the front frame rails horizontally over the rear frame rails. I'm thinking there is more horizontal forces in the front area over the rear section because of the recoil spring binding and coiling as it compresses. I switched from a 16lb spring to a 18lb spring and when running the slide by hand the cooling of the spring sounded really bad with the original short spring guide.
The full length guide rod eliminated this spring noise.

I also feel as the spring coils on the short guide rod were losing the smoothness of the recoil action. The spring is fighting to compress.

Note, if you remove the slide and empty it then run it by hand the disconnection bumps the slide kind of hard as it cycles. I machined a disconnection ramp so the bump is eliminated. It cycles silky smooth now.

Don't forget to lube your recoil spring on the guide rod and barrel bushing. I use moly on everything even the frame rails.

Picked up 100 rnds of TulAmmo 230 gr at Walmart today.....couldn't resist as it was only $15.39 per box of 50. Shot the MSP qualification course and a few extra mags at 15 yds, 80 rounds total.

This ammo ran just fine. First shot I noticed how much lighter/softer recoiling it was with this ammo. Also, the casings ejected only a few feet away compared to Winchester white box, which ejected 6 feet and beyond.

Federal Champion 230 gr aluminum case ammo, 100 rounds today, zero issues.

$1.00 cheaper per box of 50 than TulAmmo.

Also shoots Winchester white box 230 gr ball ammo with no issues.

Here's are pics of the SHOK-buff after 200 rounds. The top pic is of the front - the side that has contact with the slide. I'm surprised at how battered it is after such a short time. For sure it will be done by 500 rounds.

I might do a comparison with the SHOK-buff on the factory rod and spring, if I get some time.

I've been using the Shock-Buff's for a very long time and they are a maintenance item to be sure. When they get a bit ratty looking they get replaced. Do they really work, who know's but I feel better about the whole thing.

 

[Bob O]

If I have to change it out every 500 rounds, that's fine with me.
I feel better having this installed seeing how hard it gets battered....better it than my frame and slide.

Using the correct recoil spring for your load is more important. I use an 18 lb spring for 230 ball loads and my major 200 gr loads. I use a 12 lb spring for my soft bullseye loads. The proper spring keeps the slide from battering the frame.

 

[Bob O]

I already have a 20 lb spring in the pistol, which is definitely heavier than the factory spring. All the ammo I've shot has been 100% reliable. Some of the ammo only ejected and landed a few feet away. The more powerful rounds land 6+ feet away.

I'll see how the SHOK-buff looks after a couple hundred more rounds.

 

[Bob O]

As of today, I have about 900 rounds through the pistol, about 600 with the SHOK-buff. It's not torn but the groove is pretty deep.......it will be done for sure by 1,000 rounds, which is the recommended replacement interval.

I will replace it tomorrow when I clean the pistol. So far, not a single malfunction.

Shot at 50 yards today just for fun. When i figured out that POA=POI even at this range, I managed to ring the steel plate three times in a row.
