Cleaning a Walther GSP Expert

Post by ssauer2004 on Sun Jan 05, 2014 11:51 am

New to the forum!

What products are people using to clean their GSP Experts?  I have been using Breakfree but was looking for some new ideas.  The lower portion of the GSP Expert is not made of metal, so is there any products you stay away from?

I use the CLP on the barrel and upper mechanisms. 
 I use only a good flushing with WD-40 as instructed by Earl's Repair Service, whom I bought the gun from, for the trigger assembly. Remove the trigger assembly and spray it out good. Set it aside to drip dry on a rag. He also sells a pure brass brush for the barrel if you need to brush it. This is my 3rd year with the gun and have had only 1 fail to feed (I allowed wax from the CCI SV to build up on the feed ramp) and 1 fail to fire (dud round). This after about 15,000 rounds. Exceptional reliability with little maintenance. Smile

I appreciate the reply.  I also purchased my GSP Expert from Earl. I have never had a malfunction since I've owned the gun.  I usually use Eley Sport and SK Standard rounds. I also always keep magazines clean.  I'm not a fan of the CCI wax build-up and discontinued using them.  I use a nylon brush to clean the bore.  I guess I'll just continue to use Breakfree.

Cleaning GSP Advice

Post by ae1m on Sun Dec 06, 2015 10:12 pm

I am new to my GSP Expert.  Have over 1000rds through it.  Have cleaned the bore and whatever I could reach in the barrel.  Saw the advice about taking the trigger assembly out and douching with WD40.  Can you comment on taking the barrel apart?  Any surprises?  I see the instructions of pushing a small pin through the hole and taking the cocking lever out, what happens next?  Easy to take apart and clean?

Thanks,
Bob

Once you push the cross piece out, it comes apart about as far as you need to go. No real surprises. I just follow the owner's  manual step by step. It is easier than many other firearms I have. Hope this helps.

Thanks for the reply.  My manual has one sentence on this topic, how to push a pin thru the hole and remove the cocking lever, nothing furhter, not pics or drawings beyond that.   I will go for it.  I have many other guns, all seem to have some details it is imortant to know something about when field stripping, so I was just a bit concerned.  Not many around, so not many to discuss with!  

Again, thanks for the reply.

I am looking for guidance taking the bolt apart.  Nothing in the manual except push a pin into the hole and push the cocking lever through.  What next?  Are there springs inside, how far down further to clean.  First gun I've owned where there was no Youtube video showing!

{Second try ... my computer glitched the first attempt}

I have an original GSP, not the Expert, but I believe that I know what you're referring to. 

There's a small hole directly underneath the cocking lever in the upper receiver.  By pushing a toothpick (or similar tool) into this hole you can depress the small spring-loaded pin that holds the cocking lever in place.  While you are depressing this spring you can move the cocking lever to the side and it simply slides out of the bolt.  Once the cocking lever is out the bolt will slide out the front of the upper receiver.  There aren't any springs that will fly when you do this.

The cocking lever is held in place with this small spring-loaded pin, it just needs a bit of a push to allow the cocking lever to slide out.  For reassembly you just slide it back into place until the pin pops into the same hole.

Regarding ammunition, if the Eley Sport is the "Mexican Eley" that I once possessed (and in a full case quantity), I would avoid it.  I found it to be dirty and underpowered for semi-auto's.  Fortunately the GSP is a very clean shooting pistol.  I used it in my Victor and it gunked up in nothing flat.  I'm a big fan of CCI standard velocity; a little more ooomph to cycle the pistol and reduce bore time and by far the most reliable primers of any rimfire round in their price class.  But to each their own.

Let me know if my disassembly explanation doesn't make sense.
