1911 Long Slide (6") recoil spring length?

So I was at the local gun show this weekend and an old man was selling some of his collection. One of the guns that caught my eye was a 6" 1911 Stainless... The tag said High Standard, but the frame said Safari Arms... I wasn't going to argue over that point... Anyhow, the gun was a little dirty but the slide was nice and tight and practically no wear.

So anyhow, I couldn't pass up a good deal so I bought it. Took it home and fired a few rounds first, worked great. Then I decided to take it apart... oh boy...

The spring is literally 10-1/4" long! It also has a two-piece full length guide rod. Just getting the spring back in was quite a chore, it kept wanting to bend and flop every which direction. Then trying to get the guide rod worked in all the way to screw it back it... sheesh! I'm starting to think that is why the previous owner wanted to sell it, and I bet never cleaned it! lol...

So... is a 10-1/4" recoil spring sound about right for a 6" barrel? Or is my 1911 just "gifted"? lol...

I emailed Olympic Arms (bought Safari Arms a while back) to ask them, if I don't get a reply I'll try calling tomorrow. Just thought I would get some feedback from people here too.

Okay, so I'm just going to assume the spring is meant to be that long just because of the strength...

Hopefully tomorrow I'll have enough free time to call the manufacturer just to double check.

Haven't had a chance to really shoot it yet. Planning on going to the range Friday.... (If I can wait that long!)

Well, didn't get a chance to go to the range when planned... Hopefully this Friday now. *fingers crossed*

In the mean time I was able to call up the manufacturer and talk to someone there. They use a different recoil plug that allows 5" springs to be used.

So, I did some research and found STI makes such a product (for 6" barrels). Ordered that and a spring pack from midway, which just arrived today. Fit is sooooo much nicer.
