Do you change springs in used gun?

[TMan]

I was looking at the www.topgunsupply.com web-site today and noticed that they had a spring kit for the Sig Sauer P225. That made me think about some of my used/surplus guns that I've bought over the years. I have no idea how many rounds have been through the gun, nor how long it has been since the springs were changed.

When you buy a gun that isn't NIB, do you normally change the springs? Is there some tests you can run to determine if the springs need changing?

TMan; I was looking into purchasing the recoil spring tester but it is made only for the full size 1911 recoil springs. Of the used Sig Sauers I purchased, from Individuals, all were in new condition, however, I had one which failed to go into battery so I ordered a calibration set of springs from Wolff. Turned out to be something else.

If the recoil spring on your Sig Sauer is the German factory stranded wire type spring, it is said to outlast the solid wire spring .

I don't carry the only used semiauto that I have, so I'm still using the springs that came with it. I think if I were to depend on it as a carry firearm, that it would be a good idea.

If it chokes at the range, I can deal with it. Although since mine happens to be a BHP, I'd at least get one shot off.

When I went through the Armorers Course at the SIG factory, they recommend a detail strip, cleaning and inspection every 5000 rounds or 1 year, whichever comes first. This is for duty guns. The recoil springs are usully changed then along with the trigger bar spring and any worn parts. They are cheap and will keep the gun running well. The trigger bar spring is a pretty important one. It can disable your SIG if it breaks. That said, I put about 1000 rounds through my used P226 before I changed them out.
