[Back_Roads]

 This might make everyone who got a P-17 on this deal feel a bit guilty ?

truth in advertising, continuing...

I went to Ace Hrdwre this morning, and, found about 24 drawers full of springs.  I found one that I thought to  be a great fit, but, it was too tight for the lower valve stem (there are two different diameters on the valve stem, and I only checked it on the upper, smaller diameter section - duh!).
I grabbed three springs; one mentioned, not right. The other two were longer, but, they fit. One of them was similar in its compressive load. The other a bit stiffer, So, I cut the stiffer one down to a much better length, and flattened its end to a nice flat ring, rather than the cut-off rising angular attitude, and, put a new packing o-ring on. I also added a nylock nut, rather than the original nut, as I might need to take it apart again.  The nylock nut fits perfectly, and did not have any ill effect on function.

dscn7537 shows my repacked valve stem, prior to reinsertion.

results:
I'm back to what I feel is better than where I was prior to doing anything.  I was pinging a fallen tangelo at 50', and rolling it around.

Thanks Tom, I may try that. Earl, that would help my hand, but I don't know if my wife or nephews are physically strong enough to pump it very many times.

[Earl]

I bought 2. Thanks for the link OP.  I put about 100 rounds through them all by myself today.

Has anyone done any mods to reduce pumping effort?  I don't care about power in these pistols, and I think I will have better results getting my wife or young nephews to shoot with me if it was easier to pump.

Instead of building the piston up, you can grind a dish into the center of it to reduce cocking effort and fps.  If you go too far, you can fill it back in as much as needed with epoxy.

Good suggestion.
Or, you could drill a 1/2 or 3/8 inch hole in the center of the piston "to reduce the cocking effort and fps".
The piston is about 1 inch is diameter, so drilling a 1/2 or 3/8 inch hole should work.
If you try this, please post the hole diameter and depth and the new fps.
My guess is to start with a 3/8 inch diameter hole 3/8 inch deep then check cocking effort and fps.

Some interesting mod on piston to increase speed. https://www.gatewaytoairguns.org/GTA/index.php?topic=164607.0

Received the two I ordered today.  Just in time! 

Never had one before.  They are more "substantial" than I was expecting.

My second 4 is due for today for Christmas

[Wepster]

Mine supposedly shipped Friday. USPS has not received the package yet, according to their tracking.

[killabud]

just got mine,pretty fun

Hang in there Bill, they will show up. I'm sorry it may not be by Christmas, but you still have 1 more shipping day towards that. Mine didn't show up on the tracking either and then the one i ordered showed up even one day early. So don't give up on it, they will show up. I cross my fingers for you that they will tomorrow.

Started out checking it with a digital bathroom scale. Tested between 31 and 32 pounds. Chrono'd at 425 with spread of 5 on a 5 shot group of crosman pointed 7.4 grain. Started small thinking it would be a lot faster process to disassemble and drill more rather than fill it back in. After several tries, I ended up pretty much right where you suggested. 3/8" drill, and with my caliper I measured .380" deep right in the middle. Now it is right around 24 pounds to close, and my 5 shot group is 362 with a spread of 4.

Apparently it takes a lot to go up in speed, but there's a great deal of room to work with coming down.

Thanks for the suggestion Earl.

[Earl]

425 fps and 32 pounds to close   vs   362 fps and 24 pounds to close.
Good information.
Thank you Captain Bravo.
I am glad you got what you wanted.
Did the accuracy change?
I will probably drill one of my P17s so it shoots excite ECON II 7.4 gr at 333 fps and hope for about 20 pounds to close.
It is good to see that the closing pressure of the P17s can be reduced so easily because a lot of people have complained that the P17 was too hard to close.

[Captain Bravo]

We had family coming in, and I didn't have time to check accuracy. I'll try to test it soon though.

I should say that I do have a little trouble with these sights. I think it would work better for me if I square off the front sight. Another project when I get a few minutes.

Try removing the fiber optic tubes.
You can then fill the holes if you like.
Or, you can black over the part of the fiber optic that you see when shooting with a magic marker.

I prefer SQUARE solid black front and rear sights because I only shoot targets and they are more accurate for me.

I have a small Daisy $10.99 red dot on one of my P17s that I like a lot. 
It has 2 choices for the red dot brightness.
I mount it as far forward as it will go, so my closing hand is behind it.

[Captain Bravo]

Earl, is that daisy holding up for you?  I had thought a red dot would be nice fit for this pistol.

Alternatively to that, I had thought of doing the baking powder/CA glue square sight that BB had on his blog a while back.

The $10.99 Daisy holds up good for me. 
I have one that is probably 30 years old.
I have other cheap red dots but I like the Daisy best.

I have a Crosman pistol that had fiber optic sights.
I removed the fiber optic rods and put round wood tooth picks in their place and squared them off with a dremal tool, then I used a flat black magic marker to black the entire sight.
Using a flat black magic marker to blacken sights is an old target shooters trick.
The color is "flat black" not "high gloss".

I may try both of those options. Thanks

I googled "Beeman P17 Pistol $7.50 on Amazon" and found responses on AGN, reddit and tractorbynet- it seem that GTA isn't the only group to respond to a great deal

I'm guilty for the tractor by net reference, I got two and trying to share the wealth

Ordered mine on the 1st and got them last Saturday

[BackStop]

4 more due the 28th.
