Crosman Crosman 1701P Silhouette

So much fun! I'm still shooting mine as it came from the factory. From about 2800 PSI down to 1600 PSI, I get well over 50 shots. I refill in less than 60 seconds with a cheap hand pump. I find that loading can be a little tricky with the lighter domed pellets, as they tend to turn on their heads when they go from the pellet tray to the barrel. My remedy has been to push them into the barrel with my thumb a bit and then close the bolt. heavier pellets with longer skirts don't seem to do that, but JSB 7.3gr and 7.8gr pellets do.
The gun isn't particularly pellet picky. Light pellets, heavy pellets, lead round ball and even slugs seem to shoot great from mine at 10 meters. But I usually shoot 7.8gr domes for target practice. If you're after accuracy and honing your skills, this is a very nice gun for the money. What sight will you put on yours?

Upon diving into mine to drill out the transfer-port to soup it up to 10 foot pounds with absolutely no previous experience going into Crosman PCPS, I declared my 1701P the most logically designed and well-executed airgun on Earth. Consequently, THE EASIEST TO WORK ON AIRGUN ON EARTH.
It took all of 20 minutes for me to go from utter ignorance in servicing Crosman PCPs, to increasing my 1701P's power by 300% with no loss of accuracy whatsoever. Check out that .17" c-t-c ONE-HOLE five-shot group on the left, shot at 25 yards; not to mention the .33" AVERAGE group size.
Per my attached testing notes, a subsequent B-Staley mod increased shot-count by 46%, at a cost of only 10% of the souped-up power.
I consider the 1701P not only the easiest to work on airgun on Earth, but also the best bang for the buck in air pistols. Likely also the least appreciated!

The B-Staley "tune" is simply installing o-rings between the valve-stem and hammer in order to cushion the hammer-blow when it strikes the valve stem; thereby reducing the amount of wasted charge with each shot resulting from hammer-bounce/valve-flutter. Usually quite a trial and error process, involving number of o-rings, velocity testing, and several dis and re-assemblies between chronographing.
Basics-
1) The o-rings outside-diameter should be a snug fit in the inside diameter of the tube.
2) Larger cross-section o-rings probably work better than small cross-sections (for staying in place).
3) The o-ring stack should probably exceed 1/2 to 2/3 of the amount of exposed valve-stem.
4) Rubber FLAT washers probably work better than o-rings for remaining in place.
5) Though (obviously) a pain in the ass, as seen in my 1701P testing, increases in efficiency/shot-count can be surprising.
6) "Patience, Grasshoppah."

Thanks for the tutorial. Relatively simple and inexpensive tune out side of getting it all just right. The added humor was also nice, I need that sometimes.The B-Staley "tune" is simply installing o-rings between the valve-stem and hammer in order to cushion the hammer-blow when it strikes the valve stem; thereby reducing the amount of wasted charge with each shot resulting from hammer-bounce/valve-flutter.

One of the most accurate pistols. I teeter between keeping it stock or modding it for 10 for lbs. Either way it's a great one.

This being 2024 (and counting), I figure we all need added humor as much, and at every opportunity, possible. Hence, I take every opportunity possible to distract folks from the madnesses at hand. And assuming this forum provides escape for roughly, approximately, almost EXACTLY EVERYONE posting here, might as well inject comic relief when and where I can.
Thank you for the nice feedback, '56.
HAPPY Shooting,
Ron

Great pistol. Bone stock I get 50 shots. I found this sight to work well.

As you can see, I love these pistols. Easiest guns ever to work on. I left my 1701 stock tune as I get 60 shots with 8 grain pellets that yield 390-425-390 fps......405-425-405 for 50 shots. However my 1720 and Prod definitely benefit from the Bstaley mods to help flatten out the shot curve. Excellent accuracy with all 3. 1701 not pellet picky and shoots many pellets well. It doesn't really need the tko moderator, but with it the pistol is super quiet to shoot indoors. With the Ultradot it's so much fun to target shoot as well as plink cans. I have a number of high end airguns and these get shot just as often if not more.
