Discussions of the Smith & Wesson 642 .38 Special tend to organize around consistent themes, both positive and critical.
Reliability is the most common positive. The revolver's simple mechanism and fewer moving parts give owners confidence in it for defensive use. Most report no issues through regular carry and range sessions.
Compact size and light weight come up constantly. At 14.4 ounces the 642 is easy to carry all day, and the enclosed hammer means it draws cleanly from a pocket without snagging.
Ease of operation gets mentioned favorably, especially by newer shooters. No slide to rack, no safety to manage. The DAO trigger is the entire manual of arms. That simplicity resonates with people who want a carry gun that just works under stress.
The .38 Special caliber is generally seen as a reasonable balance: manageable recoil with adequate defensive performance. Users note that +P loads are effective but produce more felt recoil, which some find uncomfortable.
On the critical side, the 5-round capacity comes up regularly. Compared to compact semi-autos with larger magazines, five shots is a constraint some users find limiting for defensive scenarios.
Sights are a recurring complaint. The fixed sights work at defensive distances but aren't adjustable, which frustrates shooters who want more precision at longer ranges.
Trigger pull draws split opinions. Some users find the DAO pull smooth and consistent; others find it heavier than expected, particularly for anyone coming from a lighter semi-auto trigger.
Price occasionally comes up. A few users feel comparable performance is available for less from other manufacturers, though most consider the S&W quality worth the cost.
