Been trying out the HW40 that I bought today. Love my P17s ( high maintenance ) but thought I should really try the original to compare with the clones. Feels a tad more solid materials wise, but not a lot. Do like the fiber optic sights in good light, and with front light the sights do the same job as blacks on 17s (silhouetted). The manual says to use oil on piston every 500 shots, as opposed lithium grease for P17s. Power and cocking pressure seem the same. Accurate straight out the box. looking forward to trouble free shooting for a while!!! That seems to be the clincher for me, IF!!! it doesn't have the leak issues of the clones it might just be worth the extra money. I know having three of the same gun may seem excessive, but, I don't think you can have too many guns!!! Now what shall I buy next?
