HW44 & hand pump

[JohnWicck]

I have a tank for airing up my HW100 and HW44. I was thinking of a manual pump for the pistol for when I travel and don’t want to deal with schleping a scuba tank around.
Ive read that it is like an Olympic event to use a manual pump. I’ve also read that it’s a good option for a pistol.
Any thoughts on this?
How long does it take and how much effort is required. (My body building days are ove)
Also if I go down that path are there any suggestions for a good pump?
Thanks

Hand pumping pistols in general is easy due to low cylinder volume. The HW44 has a 200 bar max pressure so easy with a cheap three stage pump. Avoid too much pumping. Too much pumping makes heat (heat equals moisture) and is hard on o-rings. Have fun!

20 pumps wait 2min. Then 20 more and repeat up to 3k psi. Over 3k 10 pumps at a time. The pump will last a long time like this.

Yeah, pumping a pistol isn't a big deal. I hand pump all of my pistols (AP16's, Ocelot, etc.)

I normally do 20 or 25 pumps, feel the bottom of the pump tube. If it's cool, keep going. If it's warm (NOT hot), then stop for 10 or 15 minutes, then resume.
Just keep track of the heat at the bottom of the pump tube, "keep it cool".

As you get up in pressure, the pumping will get tougher, and tougher. use your body weight.

Your HW100, you can hand pump it, but it will take a while if you start near 120 bar to get to 200-ish bar. An electric pump or larger air cylinder is better

I've been handpumping my HW44 since I got it. Never an issue. I shoot one ten shot clip then refill to just under 200 bar (20 strokes) then shoot next ten round clip. No big deal.

I have 3 magazines for the 44.
i shoot all 3 with no noticeable change in accuracy. The gauge goes into the yellow however. So you guys are saying that the only issue is that it would ne to be filled incrementally while monitoring the heat.
Got it

Just straighten your arms and slowly drop your legs and weight, easy but you will feel it in your arms the first couple of times. Like said above, a 200 bar small cylinder will be short and easy. Pump slowly so not much heat is built up.

or use a small buddy tank in 68ci or 88ci from paintball or even smaller 45ci in 4500psi. Quick easy and multiple fills
