I own a JCP .40 and C9 Comp 9mm Hi Points. Bought the .40 new for 160 bucks out the door with one mag, the C9 well used with hard case and two mags and laser (junk) for 150. Called HP and had them send me the newer design firing pin & spring assembly, extractor key and spring, and a new trigger just for the heck of it... free of charge, in the mailbox three days later which seems to be the norm.
Had some problems with the .40 FTF right off, but after adjusting all the mags never had a problem again with it, have about 1k rounds through it, all factory ammo, mostly Federal, Blazer and Magtech Guardian Gold, which my SW40VE refused to feed and the HP ate up.
The C9... no problems at all other than a squib from WWB that I will never buy again. It has about 1k rounds through it from me, and god knows how many from the previous owner, who seemed to think it never needed to be cleaned or maintained.
Yes, they are heavy, both these models tip in around 35 ounces. They are very accurate due to the fixed barrels. Not sure why someone said they kick like mules though... recoil is far easier to manage due to the weight of the slides absorbing most of it. My SW40VE was impossible to hold on target with the hotter Magtech loads, the HP did much better returning to the target with them.
Are they ugly? Yep, every HP owner will be the first to tell you that. Do they work? Yep, any problems you have will usually turn out to be in the mags. If not, ship it in and they will fix it and usually give you a new mag for the trouble. If it is a part other than the barrel, sear or sear spring, they will send it to you free of charge. Overall, I have to say I am well pleased with mine as far as accuracy, price and reliability.
