Crosman Crosman 1701P Silhouette

[Saxons]

Hi All

I am waiting for my Crosman 1701P to arrive.

How do you find this pistol

Stunningly accurate, pictured with my 1720.

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?

I have 2 and I added a stock to one of them and it makes a great little carbine.

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!

Thanks for sharing. Did you make the grips and fore-end

Thanks for sharing. Grips look great

I'm going to try with open sights first and then decide

I should probably know this, what exactly is a B. Staley mod? Tia

No, they came with a used gun. Corcoran, woods and water is the site they came from.

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." (I know; but the closest emoji I could find is this cricket. Obviously emoji designers are much too young to know Kung Fu.)

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.
