Features 

The polymer frame keeps weight at 29 oz while the stainless slide handles wear. SIGLITE night sights cover low-light use. The decocker lets you safely lower the hammer without firing, useful for transitioning from a cocked single-action state to a DA carry condition. The full-size grip works well for shooters who find compact guns hard to control. 
 

Who It's For 

The SP2022 is a straightforward choice for home defense or range use where size isn't a constraint. The SA/DA trigger requires getting comfortable with the different first- and follow-up shot weights, which some shooters prefer and others don't. At its price point it tends to compete well against other full-size polymer/steel-slide pistols.

The SP2022 generally gets solid reviews. Build quality is the most consistent compliment. Users describe it as well-constructed and durable, with the stainless slide holding up well over time. The SIGLITE night sights are mentioned as a genuine practical advantage over base iron sights.

Ergonomics come up favorably too. The full-size grip gives most shooters good control, and the 15+1 capacity satisfies without making the gun unwieldy. Reliability with different ammunition gets positive marks across most reports.

Weight is the main drawback people mention. 29 oz is on the heavier side for all-day carry. The DA/SA trigger transition also draws some criticism; the first-shot pull weight is noticeably heavier than follow-ups, which takes adjustment. Neither complaint is unusual for this type of pistol.

Overall the consensus treats it as a reliable, well-priced full-size option that does the fundamentals right.
