Where can I get info on the different part # on different USPC40. I've sent a letter to HK USA and they can't or won't give me the numbers. In variant 7 there are two trigger pulls 4lb and 8lb. What parts are different?I'd like to change mine to 4lb.

    Dear Folks: I suspect that HK wont give you the information you want for three reasons. First, it really doesn't exist as far as HK is concerned. That is to say that there is only one trigger spring weight. There is only one spring and when it is installed properly it results in about 8 pound pull. But if you'll notice, I said, "when it is installed properly." This leads us to the second reason HK wont give you the information you want. You can reduce the trigger weight by installing the spring improperly. If you take the thing apart, you'll see that when installed properly, the trigger spring sits on top of a pin. However, you can install the trigger spring so that the ends of the legs are below that pin. This configuration produces less compression on the spring and thereby gives it a lighter trigger pull. The third reason HK wont respond is that there are a couple of aftermarket companies making springs that reduce the trigger pull, but if you read your warrenty carefully, I think you'll see that any aftermarket parts or alterations void the warrenty. There are folks and companies out there who do some crazy things to HK's pistols. This causes tremendous headaches for three reasons. First, these same people send their weapons in for repair because they are broken or malfunction because of the alteration. Second, these alterations make the lawyers very, very nervous. And, third, HK Germany will tell you that they have designed the perfect weapon and therefore there can be no beneficial alterations!!! They really become rather testy when anyone suggests otherwise. I hope this helps. Regards -- Steve, a certified HK armourer. [This message has been edited by sck (edited 09-28-2001).]

    Steve, On your take about installing the trigger spring improperly, would this do any harm to the pistol if done? I was supposed to submit a post in here regarding gunsmithing work on an HK usp40c but read your response in this thread and am now having second thoughts. The gunsmithhing prices are out the roof where I am, and to top it off, Im not even sure how good the quality of the work is. -Smooth

    Dear Smooth: The short answer is "no" it won't do any significant damage. The slightly longer answer is that the when you move the trigger spring off the pin so that it rests on the frame, the ends of the spring are rather sharp and do sometimes dig into or scratch the polymer. However, these scratches are so small and difficult to see that the only person who will know what caused them is someone who has done the same thing. What kind of work were you wanting to have done? Are you speaking of the kind of work mentioned in the post above or something else. There really isn't anything too difficult about working on the USP weapons that the average person can't do with a little guidance. The real problem is that the parts as so expensive. For example, if you want to convert to DAO, the parts will cost about $80 wholesale. If you send it back to HK they will do the work for about the same price, but they will probably keep the original parts that they remove. Finally, the folks at HK generally are really nice and try very hard, but there are only about 2 people who work on firearms, so it may take them a while to get any particular job done.The next question is where are you? I'm in Cincinnati and if we're close enough for a meeting or I can be of any help, just let me know. Regards -- Steve[This message has been edited by sck (edited 10-01-2001).]

    Hey sckThe book that comes with the USP40C LEM says that different part# make the difference between the INS LEM and conventional LEMThis is what makes me feel that some special parts are used. The book only tells me the part# for the INS LEM. Thanks for your post.

    The INS LEM has "la migra" marked on each part! just kidding!Steve, I tried to check the interior of my usp40c and cant find that "spring resting on a pin"? Where exactly is this in relation to the pistol? Also, would the usp still be viable for carry in case this mod is done? Prior to this thread, I was wondering about having the pistol accurized eg. crisper and lighter trigger etc. Is it possible to use the ambidextruous safety from the tactical in a 40c? Also looking for economically priced 40c mags...okay, cheap mags.thanks,-Smooth

    Dear Folks: You're correct about the LEM number. When I was visiting HK, they told us that there would be a few differences with the then "new" LEM trigger. Unfortunately, I can't for the life of me remember what the difference was. All I can remember was the instructor telling us that assembly/disassembly would be the same. I will go the gun shop that sent me to the school and get the copy of the books I received and look it up. If anybody would like to contact me directly in order to give me a mailing address so I could send you copies of the relevant pages (I've got a scanner but I can't figure out how to use it!) my e-mail is kottsykr@zoomtown.com. With regard to "cheap" magazines, you've probably figured out that there is nothing cheap when it comes to HK. While I was there for training they showed us a special wrench they had to buy from HK Germany to remove and replace barrles on their new "plastic" rifles. Well, they were saying that this wrench which was basically just a special socket on a torque wrench cost something like $60,000 from HK. Once they had it, they had one of their customers who owns a machine shop make them a second one for like $200 and put it on a torque wrench from Sears or someplace. The point is that you're not the only one moaning about the cost issue and you might be able to get around it. Just keep looking and you might find some used mags that are less expensive than the standard new mag price. There is a fellow who has a whole page advert. in Gun List who carries a lot of HK stuff. When the folks at HK have a batch of used stuff like mags they want to sell, they usually go to one of their bigger customers and ask if they're intested and then have them submit a bid. Consequently, some of the larger HK dealers occasionally may have things like used mags at a decent price. Finally, with regard to getting a response from HK, I've found that mail and the telephone are almost useless. The only way I got them to respond was to fax a letter or just mail off the weapon with a note explaining what was to be done. Hope this helps. Let me know if anyone wants copies of parts of the manual. Regards -- Steve[This message has been edited by sck (edited 10-02-2001).]

    sckTried to e-mail you at the address given and would not go through. I would LOVE to have those part numbers. Maybe the long arm of HK read your message and killed your mail box.Gosh how much does a magazine cost? [This message has been edited by Smoky14 (edited 10-02-2001).]

    sckYour zoomtown must still be down as they still don't appear to be alive. I'll continue to try as you are the only person who at least has heard of my problem. Thanks for trying.
