Default Short Recoil Spring

I have been more than pleased with my CMP Colt/Colt circa 1918 M1911. With about 400 rounds of range time there have been very few issues or malfunctions and her accuracy is only limited by the trigger man. The only issue I have had is at times it is "slow" or "sluggish" to return to battery and sometimes requires needs a gentle tap to fully seat. I stripped her down and did full cleaning with the same results. So I purchased a new Wolff recoil spring at the recommended 16# weight. My surprise was when I compared the recoil springs side by side. As you see from the picture the original spring is an inch shorter. It also does not have a close loop end. With the new spring I have had no malfunctions and it slams into battery with no problem at all.

Any ideas on why the original recoil spring would have been shortened?

Maybe an armorer helping out a senior officer who's grip isn't what it once was??. I added a new Wolf recoil spring (18 lb?) and Shock Buffer to my 1943 Colt/RR CMP 1911A1 and it is a real bear for me to chamber a round with my grip strength. I have to push rearward with my left hand while pushing forward with my right hand. It's a no go the normal way of pulling the slide rearward with my left hand.

I have a new Springfield Armory 9mm Range Officer model that is way easier to cycle. Probably a weaker spring and much better grip surfaces.

Springs shorten over time. Always replace the recoil spring on a new to you 1911. It is cheap insurance. I believe stock rating is 16 pounds. I also run a Wilson Combat Shok-buff in my CMP 1911. Once again, cheap insurance. I have well over 500 rounds on my CMP 1911 with no issues, after I put a magazine release in that raises the magazine higher. Feeds awesome now.

That's the best way to rack a slide anyway.

The recoil spring in my CMP 1911 was short as well with no closed end. I replaced it with a 16 lb. Colt spring and like a lot of guys, added a recoil buffer as an extra.
