Thank you for your help guys!
Jaxontarget, it is funny that you mentioned Julian. I e-mailed him regarding Hammerli pistols that he listed for sale and he was very informative and helpful.
Glad to hear it. He's put up some extensive posts that go over some of the differences of the various pistols and versions as well, again, under "Nikita"
For me, at this point, any of the guns I have, or those you're considering, shoot better than I do, and think the $ investment is worth far more in bullets and range time, than hardware. Find what works for you. Ultimately its just a tool. Its the person and experience behind it that's making all the difference. Practice is by far the most valuable thing for me at this point.
Yes, one of the other things I really had issues with around the Ruger Mk III was the cleaning/breakdown. Unlike one of the other posters here, I found it to be more complex and drawn out than I'd like. Perhaps with time it becomes routine, but I didn't give it that much because I never was able to get comfortable with the grip angle. The Mk IV looks to be a vast improvement in the realm of fieldstripping - much simpler than its predecessors. Both my pistols are very easy to field strip and clean. Both are also not at all picky about their diets, especially the GSP, which seems almost immune to failures. The 41 is just a bit more finicky, but not overly so. That might be another consideration for choosing your hardware.
