I wonder if there is a more blunt option? Clearly the wedge shape allows for ample penetration, but maybe too much?

Could something like this work better?:https://www.ebay.com/itm/121878135652?chn=ps&mkevt=1&mkcid=28&var=420871193914

That's exactly what I'd like, but want something lighter.  I'd like to find something that retains the OEM tip weight os 50 grains.  The erasers attached to the #6-32 screw weighed 60 grains, 10 more than I wanted.  I may try cutting off the tip so it's blunt like those, that should shave some weight also.  But, then I run the risk of the arrow pushing through the eraser on impact.

Holy Weight Loss Batman!  It's amazing what a little light sanding, polish, some dry lube and a couple HF springs will do for a trigger!  I tested the AJP this morning after polishing the contact points and replacing the stock springs with a couple from my Harbor Freight assortment.  It went from and average of about 10 lbs 5 ounces to and average of 3 lbs 6 ounces!  I know it felt like a significant difference when I did it to the first one, but I never tested that one before I did the trigger work, and ended up putting it back to stock to send it in before having to test it afterwards.  So, now I know why it felt sooo much better afterwards!  Below are pics of the three tests.

I also happened upon a sale at DVOR right after sending the AJP in for repair, and they had the exact same butt stock I had on the old one, but this one just happened to be Dark Earth Brown!  It arrived yesterday, so instead of painting the foregrip to match the OD Green buttstock I had on the old one, this one got a brand new Dark earth Brown one to match the foregrip and trigger!  It's not a perfect match, but then neigher was the OD Green on the last one, but it will do!

awesome !!! now we know how bad the factory trigger is

Real bad!  But, it doesn't take much to shave 7 lbs of trigger pull off of it!

Sorry to revive this thread, wish I'd found it months ago when I was shopping for an airbow.  (I bought the Benjamin)  It took hrs and hrs to find out what I could've read in 10 min in this thread.  Great stuff!  I knew the trigger could be enhanced and estimated 3 1/2lbs smooth pull was probable. (most pcp's triggers can be reduced to about 1/3)  My concern was that every ounce of claimed power was needed to humanely drop a white tail.  Reports indicate it's not quite up to the 370fps.  Since their regulator is sealed, I don't know of any way to get the power up, unless;

The last question I have is:  If the hammer spring is long enough, I wonder if RatSniper, or someone, could just use a saw/dremel to shorten the plastic block nesting the spring.  Guess you'd have to destroy that item to test a lower spring strength.  OR, https://www.mcmaster.com/compression-springs/ try a weaker spring.  If the hammer spring is already in its' sweet spot and 350fps is it, oh well.

Umarex claims a 1500psi regulated pressure.  A slightly more robust spring within their sealed regulator chould get the pressure up to 1600psi likely yielding the power for satisfactory deer hunting (IMO).

I'm grateful for this thread; great info.  If someone could report a way for us pcp'ers to get an average 370fps = 52ft lbs, I'd buy the airjavelin pro in a heartbeat.

Randy,  My experience was the spring adjustment didn't make any noticible difference.  I'm not sure a lighter or shorter spring would increase velocity.  Increasing the regulator pressure output would have a bigger impact.
