![]() ![]() The real sound impulse (momentum transfer potential) histories from the same 5-shot test are shown in Figure 3. A zoomed-in timescale displays the region of peak sound pressure in Figure 2b, for the first two shots. The primary sound signature pressure histories for all 5 shots are shown in Figure 2a. Overall subsonic 300 BLK performance comparisons of the three silencers are shown in Section 6.39.2 of this review. Another notable difference between the early-time signature of the Sig Sauer SRD762Ti-QD and those two silencers with subsonic 300 BLK is the significantly lower amplitude immediately after the end-cap exit event with the SRD762Ti-QD. For comparison, the reader is encouraged to examine the subsonic 300 BLK test first round signatures of the Q Half Nelson in Sound Signature Review 6.29 and the Richmond Tactical RT30Ti in Sound Signature Review 6.35. ![]() This is postulated to occur as a result of the length and baffle quantity of the SRD762Ti-QD. One distinguishing feature of the signature shown in Figure 1 is the delayed rise to a peak amplitude after the end-cap exit event and continued low threshold of peak amplitude in the overall signature. ![]()
