I noticed my thunder 9 had a spring wrapped around another spring (2 springs on the guide)on my thunder 9 uc compact when i went to clean it for the first time. Is there a reason for this? Anyone ever try shooting with just 1 of the springs around the spring guide and see what it does? Looks like there is a bigger one and a smaller one. If i knew it wouldn't mess anything up i'd give it a shot to see what it does.

Why?

Do you remove two of the tires on your car to see if it'll run that way.  There are other vehicles that only use two wheels, so why should a car need four

Two lighter springs are more fatigue resistant and durable than one of the same tension and size.
If you shoot your UC9 with only one spring it is highly likely you will cause damage to the frame from the violent impact of the slide in recoil, possibly damaging the slide as well. Damaged frames and slides lead down a path to damaged shooters. It will also probably not feed correctly because the timing will be way out of whack.
I highly suggest against it. Highly. Really. Don't do it.

Well the goal would be to test it as being a lighter recoil spring. In my beretta I replaced the heavy recoil spring witha  lighter 11lb. spring and found a world of difference in shooting. the muzzle didn't go all over the place when firing and I shot better overall. My thinking is that since I am not finsind a lighter recoil spring for the bersa, if I used the heavier of the two on the recoil guide by itself, it may have the same effect, but I am not sure of lb. loads that would create. Is there any way to test that without firing the gun?

If it ain't broke, don't fix it.

I have an old Thunder 9 that I bought used at a pawn shop, and it has only one spring on the guide rod. It's never failed to feed or cycle, no matter what ammo I use. My 9UC and 45UC, which were purchased NIB, both have 2 springs on the guide rod. When I check the replacement parts list at Eagle Imports, I see that under the Thunder 9 they list a "recoil spring set" available for $5. Under the Thunder 40, they list a "recoil spring", available for $4. So do the newer T9s come with the double spring, while the T40s come with only one? I don't know. But Bersa S.A. has been making handguns since 1959, and I bet they have a pretty good reason for configuring the recoil springs in the manner that they do.

The only way that I could see to test the spring without firing would be to hand cycle the pistol. If you have snap caps, use them.

If the gun works flawlessly, it seems like you're trying to solve a problem that doesn't exist. Which could be a good way to cause trouble. And if you cause yourself trouble by making unauthorized modifications to the gun, you could void your warranty. Just a thought.

If anything, I would like to see a spring a pound or two heavier for my UC9 for the SD loads, I believe you would have to make some fairly low powered handloads to ever want a lighter spring in this gun. In my experience at least, a lighter spring can lead to more muzzle flip, not less unless using really light loads.
Maybe if Wolff ever removes their collective heads from their rectum, we will both get what we want.

Engineering Dept had nothing to do one day So they decided to install 2 springs   Just to see how many people on BT would remove 1 just because.

 They do these things for a reason and unless your a degreed engineer I would leave it a lone.  But its your pistol to ruin Just don't expect any  warrenty work.

Wolff has told me twice on phone  they won't make springs for cheap pistols like the Bersa.  Kel Tec and Llama are higher quality firearms than Bersa according to their spring list.

Sounds like the people at Wolff are a bunch of "spring snobs".

  I would NOT plan to test it out unless I had money to burn on replacing the gun if it screwed it up BUT it dose make me curious if removeing one of the springs would make it cycle .380 ammo....

  I havent really had experience with your other models but I carry a Bersa Thunder 9 UC dailsand have no problem at all concealing it under an untucked T-shirt.

  As far as reliability I have over 1k rounds through mine and from the box to now have not yet had a single malfunction from it reguardless what I feed it...well except the time I had a case of the stupids and grabbed the .380 ammo by accident and loaded a mag with that, they chambered and fired but didnt cycle the action right for some strange reason. lol

The .380 round sits forward in the chamber because it's shorter than the 9mm round for which the gun is designed. I'm guessing that prevents the extractor from engaging the rim of the cartridge. The round will fire, but apparently not cycle the slide. I don't think it has anything to do with the recoil springs.

Incidentally, I took these pictures because I became curious when I accidentally loaded a .380 round in a mag full of 9mm and discovered the mistake a while later. I've never actually fired a .380 round in a 9mm pistol.

Hello Bersa-Talk shooters.

 

I am new to this site and I just wanted to say Thank You to each and everyone at Bersa Talk.  I left Detention Officer service at the Maricopa Count Sheriff's Office (Phoenix, AZ County Jails) a couple of years ago and I could not decide what to carry for CCW.  I "googled" a lot of different sites and I accidently came across Bersa Talk (and I am glad I did). 

On March 1, 2008 I purchased my first handgun and it was a Bersa Thunder 380 Plus (Black, 15 round mag.).  New , on sale and one could not ask for a better, more reliable fun pistol to shot.  Based on what I have read online and after 450 rounds (various ammo from several manufacters) at the range, this gun is a "keeper".  Sorry to get off track, but I needed to say Thanks to you all.  Keep up the good work, be safe and have fun shooting.

 

Best regards, Rainman
