I received both of these Umarex blowback BB guns (Umarex H.P.P and the Umarex SA177) about a month ago and so far I have very little to complain about either of them! Both of these Umarex airguns are great value for the money and both shoot pretty hard and accurate for blowback styled BB guns. Both have long trigger pulls with the SA177 being a bit on the heavy side. Neither one has a very heavy blowback feel but there is enough blowback to make them responsive and fun to shoot. The construction on both of these BB airguns is overall very good with the SA177 being more realistic in comparison to the H.P.P. The H.P.P tends to be a more comfortable gun to shoot because of its weighty feel in the hand and lighter trigger pull.
